Are you saying that I should change my perspective from "Trump has committed war crimes" to "every other US President in modern history has committed war crimes"?
Because yes, of course the US have done shitty things to many other countries for sheer economical interest several times in history. But so far, as a European, I and many others were looking at these things with a LOT of goodwill (the allied WW2 saviors who freed us from Nazis... the land of the Free... Iraq was somehow responsible for 9/11...). We were assuming all these unilateral intervention were for some type of greater good, and that those US soldiers were the good guys. Maybe we were naive. I was, for sure (or I wasn't born yet) when many of those past events happened.
It also "helped" that we were mostly being lied to at the time of the events and most of us only got the reality check many years later, under a new and generally apologetic US administration. It's not like when Cheney died I heard a lot of people crying on either side of the Atlantic, but in the moment we were (or at least I was) completely sold on Truth, Justice and the American Way.
Funnily enough, what's new with Trump is that his might actually be the most transparent administration in US history. It's hard now to be naive, complacent or even hypocritical when you have a President who's saying all the silent parts out loud ("yeah, our US companies want that oil, so we're going to run that country for a while"), while thumping his chest in the ring, pointing aggressively to the audience and shouting "you're next! Come fight me!" to friends and foes alike.
