What is the point of fighting evil

Traditionally, America has seen itself as standing for goodness, morality, doing the right thing, Democracy, etc… Most of the voters have, at least.

Trump does not think that. Look at Venezuela: It is open and blatant colonialism, resource extraction. Trump has just come out and said that he doesn’t care if the Venezuelan people have freedom and democracy - Trump only cares about profiting from resource extraction. Now maybe America has sometimes acted like this in the past, but Trump openly stating it is new.

This open disregard for doing doing what is morally right is a new thing. Which Trump can do without consequences from Republican voter, apparently - Trump still had ~90% approval among them, last I checked.

So in conclusion, asking “What is the point of fighting evil” is a non sequitur - Trump is not claiming to be the good side fighting evil.

As another example, look at Ukraine. Rarely have I seen a more black-and-white, good-vs-evil conflict. A fascist dictator is invading a budding democracy, with the openly stated purpose of annexation, without even pretending to have a casus belli. With Putin openly doing warcrimes left and right, torturing and executing prisoners of war, threatening nukes, and sending his own soldiers on suicide “meat assaults”. And yet, Republicans and Trump seems more sympathetic to Putin than Ukraine.
