Nobody has nuked anyone since Nagasaki so you're not exactly batting a hundred here bud. I'll take flawed democracy over authoritarian corporate self governance any day of the week. Many of the leaders in the valley have repeatedly shown that they are some of the worst people in the country.
The mere fact that USG nuked Hiroshima and Nagasaki should have put a permanent black mark on its credibility and “hingedness”. Why this is in any way controversial idk. Literally a hundred thousand civilians were killed for no military gain whatsoever. Japan was already done fighting at that point
I mean I agree with you (US submarine campaign had already completely cut Japan off), but I think it's pretty obvious that the reason it's "controversial" is the fact that Japan was run by a fascist imperial government that was responsible for the deaths of millions of civilians in China and Southeast Asia. I think it's pretty hard to judge the restraint shown when the Axis powers were the ones who started attacks on population centers with events like the Rape of Nanking and the Bombing of London. Most of the the point of the UN was to ensure it never happened again, which it hasn't.
