American Hegemony or Pax Americana (post WWII until present) is the most peaceful period of human history, despite the myriad atrocities which have occurred during that period, from myriad different parties, including the USA itself
A big reason for that, as far as I can tell, is that if one side has the USA on its side, they're basically unattackable for many places since the USA is so over powered militarily and can project force anywhere
It stands to reason as the USA recedes from the world's stage it will get more violent as more nations stand at parity with their adversaries again. And we're certainly seeing wars cropping up lately as the US continues to undermine its traditional allies, bully adversaries, declare trade wars, and withdraw from agreements.
I do not disagree with that assessment, but maybe one can hope that at some point we evolve past this "us versus them" mentality that we inherited from the savannah? If so, it's worth pushing for it.
