Yes and no. The MAGA revolution is internally carried by the lower class not associated with and uninterested in geopolitics. In fact they believe in exceptionalism and don't understand why they feel exploited and don't know who is doing it. However it would not be possible politically if not tolerated by the upper class who is smelling decline (of their wealth), because competition has moved into their part of the value chain, so they do two things. One, they now support protectionism to shield from competition. Two, they wish to exploit the lower class harder, so they point them outwards to avoid a physical revolution or an amicable redistribution.

If you want to explain MAGA you have to understand it's a convenient alignment of the upper class and the lower class for different reasons.

I’d say it’s the opposite.

So much of the US government has been focused on maintaining the global hegemony, US citizens wellbeing was sacrificed.

Trump was elected in reaction to rising global hegemony, or at least the effort put to maintain it, not the end of it.

To say US hegemony is numbered doesn’t make much sense. The US economy has only pulled headed further from any Western rival, and China’s economy is stumbling to the point it’s questionable if it can grow enough before it’s population starts shrinking. Russia has been stagnant since the 1990’s.

If anything, US ability to project power is greater now than any time in the past.

> impending loss of America's stature

Impending cause of loss of stature.

It was about inflation, prices, hate toward trans and immigration. That is judging based on pre-election topics. They did not cared about geopolitics.

> Whatever preconception you have about what motivates Trump voters

By a large, based on what they themselves say and write, they wanted to cause harm to their perceived enemies and have fun watching it. That is primary reason for why conservative and republican voters vote.

So the knee-jerk reaction is to knock it all down and speed up things while making literally every human in the world hate you?

Thats dumb to be polite but not surprising when considering where it comes from. Republicans simply can't admit their candidate is incompetent pos, superior ego thing or something. The incompetent part is what matters in this specific discussion, way worse than first term which was tampered by more reasonable people delegating actual tasks.
