Loyalties shift. There aren’t any contants. It’s the way the game of realpolitik is played.
Quite true! We agree! This statement that "loyalties shift" is not an even an attempt to illustrate any "realpolitik" advantage of the long American record of foreign aid. In fact, it would be more likely to persuade an objective observer that foreign aid is a failure in purely pragmatic terms.
I believe in realpolitik too. That's why I'm against foreing aid because it doesn't work, help the recipients, and produces blowback. Do you have an actual "realpolitik" evidence that the record of American foreign aid has been of net benefit?
