I believe the only reason American civilians like us have been able to enjoy peace is because we dropped a ton of bombs to blast tiny countries out of the sky and we also have a history of fighting wars not to win, but not to lose. If Americans are willing to sacrifice their people and resources for a tiny country in the middle of nowhere, imagine what they would do to you if you attacked them or their interests.
I was watching a documentary about the Schwarzman Scholars, and Schwarzman said something like out of the 4 or 5 times where a superpower was challenged by a new rising superpower, it led to armed conflict 3 times. I haven't been able to find an article to back up this claim so would appreciate if anyone could point out if it's blatantly wrong or if there's a source. Either way, there might be a new superpower.
