In recent American history. I was born in 1985 and the breakup of Yugoslavia and ensuing wars happened in my lifetime, and the Russian invasion of Georgia and Ukraine Ukraine, and things like the Syrian civil war, US invasion of Iraq, Afghanistan getting invaded by the Russians, then had a totalitarian Taliban rule, and then had the American invasion.
I mean, it sure is significant and all as the US, for better or worse, isn't "just another country", but it's also pretty narrow towards both the current time and specific location.
But we’re not just talking about the US. Tensions in the Asian region are at the highest since WWII as well: North Korea and South Korea. China and Taiwan. China and Hong Kong. Then there’s China and their increasingly imperial motives in Africa and the Asian sea. Plus increasing conflict with the US.
Then there’s Russia and Ukraine. Turkey and Armenia. The Middle East conflict with Israel, Europe, and the US.
So no, it’s not just American history. Globally, things are the least stable since WWII.
