I'm sure this is a compelling point to you, but it's opinion. That's it. If Harris wins and the wars continue and expand then they are happy, and under her, they will.
If Trump wins and they continue and expand then hey, I was wrong, oh ah big deal, the USA has been waging proxy wars and regime changes since the 1950's so it's the same again. I won't lose sleep about it.
But if he doesn't or lessens them, then I'm right, less people get killed. Great!
But either way it will have absolutely no affect on my life as it stands. Just as the last 8 years of Trump/Biden didn't either. It's just an intellectual exercise. A move perhaps of the USA Overton window, a continued migration/realignment of demographics between the two parties.
And ultimately what I consider to be the real change that is world occurring of an increased tendency toward isolationism that if some of the economic/demographics collapses occur in Japan, China, Russia, and more coupled with more xenophobia, this will accelerate in the USA.
And who ever gets election now and after will only be a symptom, not a catalyst or a solution.
