Sure, that's one way of looking at it. But the truth is that there is only one force for civilization in the World today and that is America. The end of USAID illustrated something: America stands alone against the entropy of nature. She is humanity's only vanguard against ruin. The Chinese are dedicated to their own advancement, the Indians are currently bootstrapping out of poverty, the Europeans are primarily concerned with wine, cheese, and luxury goods. Fair play to all of them - may they live in peace.
But one nation, alone, fights Humanity's cause. Trump et al have cast off the mantle, but it's only another 3.5 years and we have a shot at donning it again. The nation is not for the people - or we would simply rapaciously consume its resources to feed the present. The people of the nation are not for the nation or we would consume them to fuel the engine. The nation and the people are both there to advance the principles of the group into the future. And I believe America's principles deserve to exist into perpetuity so long as they adapt to meet shifting weather.
Ask not what your country can do for you. Ask what you can do for your country.
All USAID showed was now the grift machine works--most of that aid money was getting kicked back to corrupt politicians to pay for campaigns. Other monies were being siphoned off in the corrupt nations that accepted the funds. Those NGOs advertising for more "migration" were doing on the US taxpayer's own dime! So I don't know if we can draw many conclusions from it other than it created some money velocity in various forms.
America's cost of living crisis is in large part due to the huge carrying cost of all that graft--it wasn't illegal, mind you, just unethical.
Sorry, but I don't care about the self-interest of my nation in any matters that don't concern the self-interest of her citizens, much less any matters that work directly against the self-interest of her citizens—and no amount of rhetoric is going to convince me that I should think otherwise.
Europe (as a whole) gives more money absolutely and multiples more in proportion to national income than the US. The US does (or did) have very good distribution networks, and that’s not liquid in a monetary sense.
I would encourage you to examine your statements on rapacious consumption of resources and people as well.
