Oh yes, of course I realized the sarcasm there...
I also understand how, in the long-term, isolationism may not be the best policy decision, especially not for every country.
Yet, in the case of the US, it would make sense to try to fix the damage we have done throughout the world by disengaging.
I woudl also go so far as to say that US foreign policy from the latter decades of the Cold War onwards was so destructive around the world that, to be honest, to be proper, we have to be tolerant of the tyrants that have risen up in the vacuum of the geopolitical chaos that we created.
We need to be isolationist in part to correct the wrongs of what we've done.
