It's interesting, because I initially thought these restrictions in UAE were strictly because of operational security. That is why Israel and Ukraine, for example, also forbid posting images of missile impacts: it provides valuable targeting information to the enemy. In Israel the legal framework is military censorship; in Ukraine it's martial law. Enforcement against individuals is strong in Ukraine, and more selective in Israel - presumably because Ukraine has a bigger internal infiltration problem, or perhaps because Israelis are more disciplined or have more effective social pressure?

In any case, in turns out I was mistaken: apparently in UAE the wave of arrests are not framed as operational security, but a wider ban on information that could "spread misinformation", "cause panic", "affect national security", or "damage reputation". So it's a wider legal framework with more complicated implications - less of a no-brainer than I initially thought!

No, most likely Iran actually launched missiles targeted at the Oracle datacenter, but they were intercepted. The UAE successfully intercepts about 90% of incoming Iranian drones and missiles.

Then Iran then claims the attack was successful for domestic propaganda purposes, and since there is no internet in Iran, nobody can verify if it was actually successful.

Datacenters aren't categorized for warcrimes. Desalination plants, water treatment plants, power plants, etc. would be highly significant for millions of the population.

What motivation would Iran have to not commit war crimes?

It's not as if the US and Israel are restraining themselves from committing war crimes. Certainly the UN isn't going to step in and do anything.

This war started with the US committing a war crime (blowing up a girl's school).

Outside of the countries involved, Is it really a war crime though?

If Oracle's providing services to your enemy's army aren't they a "legitimate" target just like a tank factory?

Are there any military personnel working at the Oracle Facility? Big Tech is very much used in this War so not a stretch to imagine military personnel working there.

Apparently the hotels that were struck in Dubai etc were attacked because US military personnel were working remotely there due to US bases being damaged.
