Well for one thing the US genuinely seems to be a lot less imperialistic these days. I mean, not militarily at least, I'm sure they are still involved in all kinds of meddling but with less military muscle flexing. It started with Trump but Biden seem to thankfully have kept the same less-interventionist policy. So I guess they have found a way to not do the other stuff, thankfully.

I guess it could just be a return back to the mean from the absolutely, unashamed military imperialism of the 1980s- early 2010s.
