If you hadn't noticed we've got our own fascist theocracy attacking its own people in the western world. We're trying to avoid giving it any more energy with vaguely-defined popular policy goals. And staying out of another country's affairs, regardless of how evil those affairs are, is a valid moral pillar.

Now perhaps there is an interesting academic discussion about whether if we had done more to direct Demented Donnie towards Iran, that he wouldn't be attacking the rest of NATO trying to steal Greenland to create some dipshit's idea of a legacy. But that is hardly definitive with the kind of moral clarity that you're asserting.
