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.
