    If they weren't planning on making nukes before, they for sure are now. Good job everyone involved!

    Just couldn't wait for diplomacy to play out.

    • mrtksn3 days ago
      They for sure got determined making the bomb after the diplomatic solution was bombed by Trump in his previous term.

      IIRC, Iran appeared to comply with the terms of the agreement and once that was out of the window they no longer complied.

      • bitsage3 days ago
        Iran was hiding nuclear material during the duration JCPOA was active. They were declared in violation of the NPT by the IAEA recently for actions undertaken between 2009-2018.
        • mrtksn3 days ago
          You're right that the IAEA has indeed pointed to Iran's past undeclared nuclear material and activities, leading to NPT safeguard violations for the 2009-2018 period. However, it's also important to distinguish between those historical undeclared issues and the specific JCPOA compliance. For the duration it was active and before the US withdrawal, the IAEA consistently verified that Iran was adhering to its JCPOA commitments regarding its declared program. The argument is often that while those past issues were concerning, the JCPOA still provided a robust framework for monitoring Iran's active program, which was then dismantled
          • bitsage3 days ago
            Iran was objectively not in compliance though [1]. The IAEA just didn’t know they weren’t so they gave Iran a seal of approval. Israel had always claimed that Iran was hiding material, which convinced Trump to leave the JCPOA, but the IAEA could only corroborate it later.

            Perhaps we should be making the argument that Trump shouldn’t have only gonna off of Israeli intel, but he ended up being correct that Iran wasn’t correctly reporting their enrichment stockpile, which was a provision of JCPOA. The reason why JCPOA wasn’t revived is actually because of Iran refusing to cooperate about what they did with the undeclared nuclear material.

              Yeah, that's not very honest position. You have to decide if you want to squeeze them out or make things right.

              If they hid things and the agreement wasn't just trashed, that could have been a scandal that gets resolved on the path to peace. It could happen for many reasons, maybe they don't trust the West to uphold their part and wanted an insurance policy, maybe it was division within. It doesn't matter that much, it's not like they made the bomb already and were about to hit once everyone lowers their guard.

              Later what we had was Iran that was on the table, trying to play nice and that was destroyed probably because of the ego of a guy who couldn't handle to stick with the agreement signed by someone he hates.

              • dilyevsky2 days ago
                Interesting way to play nice by having dozens of secret sites that nobody knew about (nuclear archive) and recently taking enrichment to 60% (they've been caught with over 80%) and dabbling in metallization which have only military applications.
                • mrtksn2 days ago
                  Well, whoever did that was proven right(from their standing point + Ukraine). Apparently you can't trust USA and give up your nukes. If you don't have nukes they don't honor the agreements and guarantees and even bomb you.

                  Unfortunately the American attitudes will result in proliferation. Not the Iranian ones.

                  • dilyevsky2 days ago
                    Giving up nukes was never the intention. They would've slow-boiled the frog and we would one day wake up with a nuclear iran (with icmbs! - not banned under jpoa) if they were smart about it like dprk. Unfortunately for mullahs they weren't and got cocky and overextended. Then 10/7 happened and the rest is like they say history
                    • mrtksn2 days ago
                      Maybe or maybe not, we will never know that. Who knows how things play out when a country is integrated back in the international system and have something to lose when if get caught on checks. Maybe there would have been a book about how Iran continued its clandestine nuke program but eventually dismantled it as its society and economy normalized and having that had no benefits.

                      Now we know the timeline where agreements are not honored by the US.

                      • dilyevsky2 days ago
                        OK but we actually kinda do know that because there were sunsets in that deal which meant we would've gotten here just a few years late.

                        > Who knows how things play out when a country is integrated back in the international system and have something to lose when if get caught on checks

                        Ah that's the Merkel's school of international relations =) We also know that with a russia example which you mentioned. Didn't work too well, did it?

                        Btw, DPRK were also given many concessions and reintegration opportunities (Kaesong) yet that was not the path they chose.

                        • mrtksn2 days ago
                          Look, I don't know why you believe so much in the imaginary timeline but maybe Iran would have been like Israel: having the bomb and not talking about it.

                          Who knows, it's all speculation at this point. The current reality is that if you don't have a nuke you get invaded. Everyone will have nuke soon. Those who fail will be destroyed because agreements, international laws etc doesn't mean anything anymore.

                • florbnit2 days ago
                  Why are you suddenly arguing against Israel? I mean he’s we know they have hidden nuclear weapons and will not enter into any deals or allow inspection. But they are on our side so we don’t care about that.
                  • dilyevsky2 days ago
                    silly argument. iran is not a tiny country surrounded by much larger countries that want to run them into the sea. they should have invested that 500B into conventional forces instead - be a lot safer for that as a country (except that would threaten the regime).

      yea enriching uranium to weapons grade in a secrete underground lair indicates no intention of developing a nuclear weapon.

      Trump peddled back from the contract and negotiations of nuclear disarmament in his first term. So yeah, it plays out exactly like he wanted it to be.

    You don’t need to be a genius to figure out that centrifuges installed 70–80 meters underground will be largely unaffected by bombs which are believed to have an effect down to a depth of 60 meters.
    • swat5353 days ago
      The New York Times reported on Saturday that they had lost track of 400kg of 60% enriched uranium, which could yield 9-10 nuclear bombs:

      https://nytimes.com/2025/06/22/us/politics/iran-uranium-stoc...

      According to Israeli media, it is not known whether the Fordow underground nuclear complex has been destroyed.

      Netanyahu has already declared victory, but Iran's nuclear capabilities will likely be completely restarted, most likely within a few years or some estimations says months.

      There is no doubt that during that time Iran will strengthen its aviation, intelligence and reconnaissance, which have now failed drastically. "Regime change" goal for Israel also failed.

      Many more Mossad agents and collaborators will fall in Iran over the next few months as IRGC begins its crack down and Israel will surely lose a huge portion of their main weapon. Further TRUMP declaring "no regime change" today, made this matter worse.

      Iran practically has a script for its problems now. Israel has learned what will happen when Iran gets thousands of their hypersonic missiles and fixes the problem with the lack of launchers which Iran will certainly continue to produce.

      Only a ceasefire has been achieved, but there will certainly be a second round (likely by Israel again once more intel is gathered), because a war like this never officially ended.

      More importantly, let's not forget who paid the price at the end? As always, innocent Israelis and Iranians who never knew each other or had a problem with died.

        A bomb is much cheaper than a factory. That was the message of this bombing run: try to restart you nuke game again, and we’ll bomb you again. And that time we won’t stop until we topple your regime.

    • ramshanker3 days ago
      Moreover, I read the wiki ( https://en.m.wikipedia.org/wiki/GBU-57A/B_MOP ) that 60m penetration specification is for ~35MPA concrete. And good basalt rocks easily go 100MPA. So if Iranians choose just good Mountain, and there are plenty of them...... Mother earth is really strong some places.
      • mgiampapa3 days ago
        That's probably why they targeted the air duct system. It's already been cut and provides a blast channel.
        • LastTrain3 days ago
          Ah, the Death Star theory
        • mrtksn3 days ago
          They probably have blast doors on those and USA made it very clear on Flightradar24 that the bombers are coming, lock the doors.

          I would assume that this thing is entirely compartmentalized, so to destroy everything you will need a bomb in every room.

          According to wikipedia, US made around 20 of those bombs and Trump used 14 of those. So %70 of the stockpile is gone in one go.

          Especially on the main site they dropped 3 bobs per strike location, so at best they could have destroyed 2 compartments with 6 bombs. If those were able to penetrate of course.

          Honestly, it looks like it was a show like the one where Trump fights professional fighters on the ring. Just significantly more expensive.

          Maybe they should just generate those images in AI, would be much more cost effective propaganda.

            And now we've learned that these weapons were purpose designed and built specifically for this mission back during the Obama administration:

      Overpressure... as the Russians taught to the Afghani's, a small explosion in an enclosed space does massive damage to both soft and hard materials.

      You don't have to blow something up to destroy it.

      • ethbr12 days ago
        Centrifuges and driving equipment, sure.

        But U-235 doesn't stop being U-235 because you pressurized or heated it up. Can't blow up atoms.

        Best case, instead of a pile of enriched uranium, you now have a highly concentrated mine.

        Sure, you'd have to separate it again, but getting U-235 away from dirt and rock is a lot easier than separating it from other uranium isotopes.

        Even if it was stored as volatile UF6, what, you've converted it to UO2F2 / U3O8?

        • FuriouslyAdrift17 hours ago
          They can buy enriched uranium from at least 2 sources...

          The expertise and equipment to develop and maintain a nuclear arsenal at scale is vastly more important.

      • bitsage3 days ago
        I find this argument hard to believe. Israel had complete air superiority for a week and was monitoring all the sites, routinely hitting the above ground nuclear facilities. I’m skeptical Iran could transfer anything significant from Fordow and not be immediately spotted by Israel.
      • votepaunchy3 days ago
        This has been repeated so many times but the enriched uranium is far more vulnerable in transport.

        • cwillua day ago
          Most modern goods are valuable and hard to replace because of their mechanical or chemical properties, and so blowing them up destroys the value.

          My understanding is that U-235 is not like that, blowing it up accomplishes very little when recovery consists of what they'd already be doing to clear the debris, plus some mechanical and chemical separation.

          Of the guys I graduated with, half died either in Iraq or Afghanistan between 2002 and 2006, or killed themselves shortly after returning home. The other half are broken. Either physically or mentally.

        Nukes or ground invasion, the point of the attack wasn’t to knock out the facilities, it was so that Trump can be dragged along ‘reluctantly’ so he can sell the conflict to his base. It is a persuasion technique called mirroring. Trump mirrors the position of the anti-war base, then slowly piece by piece he changes his position bringing his base with him. I guess how far it’ll go will depend on how effective the state is at suppressing anti-war sentiment. If history is a guide then the state can be surprisingly effective at this.

          I expect there is no desire on Trump's part for a long game, and he just took an isolated opportunity (Iranian air defenses smashed and air force suppressed) to wave the flag and look militaristic.

          Limiting the strike to nuclear facilities also provides deniability to Iranian civilians that, unlike Israel, the US isn't looking for a full scale war.

      Really? I think calculating the achieved overpressure to whatever structure underground after 6x 30k pound bomb impacts is far into the “genius” category. I’d wager you’d need a team of pretty smart people to even begin to get a wrong model of that.
      • cjbgkagh3 days ago
        No genius needed, but all those involved are motivated to lie about it. The bombs have a depth range and 200ft (60m) is the optimistic depth for ideal conditions. These were far from ideal conditions as the location was specifically chosen to resist this. That and ultra high performance concrete is now a thing. This is why the entrance and exists were bombed and those are easy enough to dig back out again. The attack was telegraphed so advanced preparations were made. It is rumored that the entrances and exits were packed with dirt in advance to minimize the damage.
        • RationPhantoms3 days ago
          I don't know if it's only effective depth of the ordinance that matters here. Positive interference could be used to amplify the explosive wave of the 6 bombs that were dropped with accurate-enough timing.
          • cjbgkagh3 days ago
            If you were going to do that you wouldn’t waste energy breaking the rock to begin with. I highly doubt it’s feasible to time things that accurately and even if you could there is a lot of mountain in the way to soak up the energy.

            The depth assumptions for the facility are often with a shallow gradient roads for the entrance and exits, but there is no need for the gradient to be shallow.

          • maxglute2 days ago
            It's a pretty dumb ordnance, gravity delivered GBU57 is a physics bound problem. The dimensions etc are known, you can give it the most optmistic assumptions, i.e. complete steel for max penetration, release at altitude where it reach max terminal velocity without grid fins deployed, run that through ndrc/young pentration equations etc. There aren't any super secret parameters for subterfuge like electronic warfare. Eitherway there's public videos of GBU57 in action - grid fins deployed to hit a traffic cone - defense autists counted frames, did napkin math, it's more or less what's purported ~ mach 0.8-1.2 penetrator designed for ~60m concrete. IIRC the assume sphere cow math for heavier all steel, no grid fin (i.e. not accurate), max out at mach ~2, doubles energy, penetrates ~80m.

            On the other hand, Fordow's construction time is known... as far as I know, many years before fgcc / uhpc and other "advanced" concrete formulas PRC formulated against US penetrators. And Israel probably has entire blue print, so who knows. E: quick lookup and GBU57 seems to be revealed shortly after guestimate of when Fordow started construction, possible Fordow could update design in anticipation, but then again, B2s were known entity and Iran's engineers can probably guestimate out what the maximum size/weight penetrator US could deliver on B2s before knowing GBU57 existed.

            • anabab2 days ago
              What if it has some sort of a booster to increase its kinetic energy just before the hit?

              Also the behavior might improve in an area already weakened by a ventilation shaft/previous hit (first bomb turns 40 meters into fine gravel + detonates weakening quite a large are, second and third bomb easily go deeper)

              • maxglute2 days ago
                I think 1) is unlikely, b2 bays can't fit much more, gbu57 is mostly metal and no booster for penetration 2) is what no one knows, but we (as in the public) also don't know layout/construction, i.e. actual depth, bunker design (can emb sloped concrete/steel layer to deflect penetrators laterally so follow up drop don't go straight down).

            The math isn’t that hard and the ideal case is a linear extrapolation so people can sit down with a calculator and figure it out.
            • buildbot3 days ago
              The math is really that hard? I have no idea what the soil or rock is, what happens when the first bomb hits it, the second, and then the third? Does the timing matter? Does the timing matter if it's 5 minutes between? 1 hour between? Seconds between? Does the type of soil or rock compact or loosen when bombed? What's the variation in explosive yield? Does the ground transfer force from a shockwave well or poorly? Does that change after the first one?

              I really doubt this is very linear.

              • cjbgkagh2 days ago
                For it to be super-linear an additional meter of concrete / earth / whatever must be easier to penetrate than the one before it which I would classify as a physical impossibility. This is why linear is the ideal case.
                • ethbr12 days ago
                  Not with regard to multiple bombs.

                  > Does the type of soil or rock compact or loosen when bombed?

                  Is the most relevant question.

                  It seems reasonable that fractured rock may be easier for subsequent bombs to penetrate.

                  • cjbgkagh2 days ago
                    Even if I were to accept the dubious premise that there is enough fractured rock to make a difference and there is no hampering with rocks falling into the void and that it's possible to hit the exact same spot repeatedly without touching the sides, all that would do in big O notation would be increase the constant factor. It would not be super linear after the second bomb.

                    If your are talking about bombs that hit side by side then clearly that is sub-linear as no matter how fractured the rock it’s not easier to push through than air.

                    • ethbr12 days ago
                      An explosion creates a pressure wave. A pressure wave fractures rock. Fractured rock may be easier to pierce than solid rock.

                      Ergo, if first bunker buster penetrates to maximum depth -20m and then explodes, fracturing rock within a __ radius, then second bunker buster travels through that fractured rock, the second (and so on) may be able to penetrate deeper.

                      I have no idea about the physics of penetrating fractured vs non-fractured rock, but it's a physically plausible mechanism.

                      Furthermore, given the multi-minute timeline reported, there's enough time for the bombs to be deployed sequentially.

                      • cjbgkagha day ago
                        In the linear case a bomb twice the size goes twice as deep.

                        Take a bomb, cut it in half and drop each half separately, one after another into the same hole, would you except the cumulative depth to be greater than the whole bomb or less? Consider that in the case of the whole bomb it is equivalent to two halves arriving at the exact same time.

                        • ethbr1a day ago
                          It's not about bomb size.

                          It's about bomb quantity and sequential effects.

                          • cjbgkagha day ago
                            Scaling is about bomb size, that’s what linear was referring to. No one is arguing that multiple bombs can’t ‘drill’.
                            • ethbr1a day ago
                              Gotcha. Sounds like we're in agreement, then.

                              The strike may have been able to achieve greater penetration depth with multiple sequential weapons impacting the same point (i.e. the three seen in satellite imagery).

                                  I'm confident that 'drilling' with multiple bombs was the known approach prior to the attack. The planned approach to soviet bunkers was to use repeated accurate strikes of nuclear bombs to achieve a similar drilling for their bunkers.

                                  There appears to be an assumption that the main facility was exposed to blasts from the tunnels and since that appears to be an obvious weakness I'm wondering why the Iranians wouldn't have blast doors between the tunnels and the facility as a form of redundancy. I am still worried that this is part of an approach to slowly warm Americans up to another war, much easier to sell a limit strike as a success, then 3-6 months later when the Iranians have recovered it'll be even easier to sell another strike or a more involved engagement.

                There are physical limits to weight, hardness, max explosive energy and max kinetic energy and these are all known. The only way to exceed them would be to drop it from a higher altitude, like space, or give it a nuclear warhead. The US isn’t the only country that has tested bunker busters and the physics involved isn’t that hard. It’s just expensive.

                  Sure, but you have no firsthand knowledge of that information.

                  You are told the B2 can carry a certain payload weight.

                  You are told the B2 has a certain operational ceiling.

                  You are told the bombs are a certain weight.

                  You are told the bombs are made from a certain material.

                  You are told the bombs contain a certain type of explosive.

                  Everything you know about this device and its capabilities came from an organization that has every motivation to publish specs that are just enough to raise the eyebrows of the people this device is supposed to scare hell out of, but they have less than zero motivation to publish specs that speak to maximum capabilities.

                  So while your calculations might be accurate for the component values you gave it, your component values of your calculation are not accurate, because all you know is what you were told.

                          Gotcha. So your perspective is there are other entities making airplanes with the capabilities of the B-2 and a bunker buster bomb equivalent to the GBU-57 so much so that you can reliably determine capabilities of those weapon systems…as a layman with just a hand calculator?

                          That is a $2B aircraft and a $20M ordinance (each). You want to tell us exactly what entity has anything even remotely equivalent? No one else but the US could bear to afford it. Maybe China…but if they have it’s not common knowledge.

                          I think you have pretty much dug yourself a hole here on your knowledge and capabilities…you have landed into silliness now. (That pun was definitely intended)

                            No amount of money enables an aircraft to violate the laws of physics. Clearly your knowledge on aircraft is limited otherwise we would have a shared understanding of the physics involved and wouldn’t even be having this argument.

                              But perhaps you can figure all of those values you need by just knowing the wingspan and airspeed of the aircraft delivering the payload, if so…I defer to you and this amazing deductive knowledge that you possess.

        This is not a "genius" problem. This is mundane number crunching that every military has been doing for hundreds of years with ever increasing accuracy.

        You need a few bombs and some places of varying geology to set them off. You take those data points, cross reference with all your historical knowledge and should be able to say whether a bunker of given construction a given depth under a given geology can be breached.

        I hate how allergic to just testing and prototyping things modern engineering culture is.

    The status of Iran’s nuclear sites (and more importantly, its stockpile of enriched uranium) is anyone’s guess at this point. It’s likely that no one truly knows, not even the Iranians. It will take significantly more time to get a clear answer.

    That said, it may not matter much. Restarting their nuclear program in secret would likely be far more difficult now and would almost certainly be detected. Ideally, a political agreement will soon render the issue moot.

      The project is dispersed and hardened enough that a single attack probably wont' be a decisive blow.

      The surprising thing is that Iran doesn't have an atomic bomb yet. Enrichment is the hard part. Building an A-bomb from enriched uranium is not that difficult. The technology is 80 years old and most of it is well known. It's no worse than building, say, an auto engine from scratch, something racing shops do routinely.

      H-bombs are another matter. Those are hard.

    It probably damaged them to some extent. Sensitive machines don't like dust and vibration. Bombs are known to cause a lot of both.

    From a negotiation standpoint, you're in a weaker position if the enemy's killing machines can cross into your territory virtually unopposed and strike what should be three of the most secure locations in Iranian territory. Both the Israelis and US managed to seriously compromise Iranian territory recently, and while the Iranians could probably draw blood and destruction on American territory if they wanted to, they couldn't do it to the same extent.

  • omegaworks3 days ago
    Worth it to keep in mind as well, that Iran was committed under the NPT to limit nuclear development to non-weapons based usage. They were inspected regularly by UN bodies like the IAEA and the conclusions of our own intelligence agencies did not support the assertion that they were developing a weapon.

    They were using it to support a legitimate nuclear energy and radiotheraputics industry. They are in the part of the planet that will be most impacted by climate warming, so nuclear is critical for them to support baseline power needs.

    The United States striking these sites throws the entire international system of non-proliferation into question. If there is no commitment any country can make to any system of governance that allows for peaceful development of nuclear energy, there is no controlling nuclear weapons development and proliferation.

    Nowhere in this CNN brief are we informed about whether the sites were or were not used for weapons development. If we take the lessons of mainstream media's coverage of the Iraq war, it is likely CNN is stating this because their owners have been told that it would be better for their bottom line to manufacture consent for a second round of strikes than to preserve the President's assertion that the strikes were successful.

    • mulmen3 days ago
      > Is it even possible to "destroy" enriched uranium?

      Yes, obviously you can cause it to go critical.

      But that wasn’t the question. A stockpile can be destroyed by simply redistributing the contents in a way they cannot be easily retrieved.

      • dantillberg3 days ago
        > cannot be easily retrieved

        This is I guess where the analysis gets fuzzy, where honest assessments may vary widely.

        My gut instinct is that enriched uranium blown up underground (assuming it was even there) would take at most around a year to recover, by turning the site into an open-pit uranium mine. The product wouldn't need to be re-enriched from scratch, as simpler mechanical filtering could probably isolate much of the already-enriched uranium.

        But perhaps it would be much harder.

        • mulmen3 days ago
          There’s no state change in the enrichment process. It’s literally just mechanically filtering isotopes.

          The point is it is possible to destroy a stockpile without destroying the contents of the stockpile.

          If you have to turn the site into an open pit mine then I am comfortable calling that a destroyed stockpile.

          This kind of strike will only ever delay the process. There’s no decisively preventing anyone from enriching uranium because the laws of physics are universal.

I guess Democracy Now! and The Nation. They don't do a ton of their own reporting AFAIK (outside labor action and issues, and sometimes environmental movement action, on which DN local correspondents are often practically the only people covering them) and are more on the commentary/analysis side.

      You can also check out stuff like the journal Foreign Affairs, for this kind of topic. Your library probably gets it, no need to pay. It's more for gauging the zeitgeist among the mainstream international politics wonk/consultant class than anything else, but sometimes contributors accidentally write something more broadly insightful, too.

      Try non-US media for foreign affairs topics. Even machine-translated French or German or Indian papers, that kind of thing, if you can't read the language. Sometimes they'll spend a lot of time on stories that have practically zero visibility in the US, and with a different perspective that's less deferential to the US.

      (Pro tip: for any story that features Trump himself heavily, and especially lots of quotes from him, it'll be 1,000% more fun to read in the BBC's pidgin English service. Try not to think too hard about whether your enjoyment of it is kind of mean to speakers of pidgin English, and just bask in the distance & shifted perspective [and, yes, humor] the language difference provides for these stories in particular.)

      X/Twitter is that thing.
