We went from 4-5 countries getting nuclear weapons in the first 15 years, and an era of about 60 nuclear tests each year in the 30 years after that, to the current era where it's about one country every 10-20 years gaining nuclear weapons and basically no tests happening. I'd say that's a massive improvement.

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.

> This past week had a test in both N. Korea and Iran

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.

Reading the news, my gut feeling is that US and China are preparing the ground for war between each other, though it makes no sense from an economical point of view, so perhaps I'm reading it wrong.
