The USA were pretty clearly on the "better side" of conflicts in 1941-1945, during the Cold War (at least as far as Europe and the Marshall plan was concerned). In Koweït and central Europe during the 90s. You may even argue for Afghanistan post 9-11 (although the state building was botched.) in the 2000s. ISIS is a footnote in history because of US intervention (from Trump first term, of all things.) And Ukraine would not be against getting the support it had in 2022 back under Trump.

Does not mean that very bad things were not happening at the same time.

But it's definitely easier to find some "supportable" interventions from the US than, say, Russia or China.
