(OT: I do not understand the U.S. policy in this, but surely they are doing everything in their power to prevent that, since this will affect, like, everything. Right?!)
And, the tension between the U.S. / NATO vs. Russia / China / Iran / (Brazil ?) has lessened, but it certainly it isn't gone. How optimistic are you?
We've also mostly stopped with firebombing, and have seriously dialed back the chemical and biological weapons that were much more popular in the WWI/WWII era.
This past week had a test in both N. Korea and Iran, so I don't think that is accurate.
> I'd say that's a massive improvement.
Oh, yes sure it's an improvement. But if we only have two countries intent on starting a nuclear war, thats already enough to hose the whole planet. And I am far from confident that we can safely say we aren't there.
Neither of these happened.
North Korea tested a missile which could be used to deliver a nuke, they haven't tested any nukes since 2017. I don't know what Iran tested, but it certainly wasn't a nuke. The only news of a missile test from Iran this week that I can find is them testing an anti-tank missile, which obviously isn't even meant to deliver nukes.
