I followed development of COVID when it happened in Asia, before it became mainstream in the west. Countries like Vietnam had contained the virus much better than western countries by faster and more decisive actions, which came from their experience with the SARS virus.
The biggest problem what I noticed is that Western countries see pandemics as personal health issue and not a collective problem. If you woke up from a coma and someone told you there was an over death of 1 million people, then that could only mean two things: war or a pandemic. Fighting a pandemic is more akin to fighting a war, than fighting obesity.
It's also worth noting that while the Republican party itself is using this investigation to its advantage, it has bipartisan support. Rand Paul is rather independent from his party, as far as senators go, and it's not just Fox News supporting his investigation but The Young Turks too (https://youtu.be/BXIP6-8GHcE); two organizations that rarely agree on anything.
I'd love to see some kind of independent body to investigate the organizational failings of the FDA and NIH and release recommendations for changes based on those findings. Given the lack of such an organization, Rand Paul is is doing the best I would expect from a senator.
Everyone is government double speaks, that part is very unsurprising.
