As to America first isolationism and some "new right wind", I'd have to have you 'splain that. We still are involved militarily in other parts of the world (LIbya, Syria, Somalia?). And I don't believe that the majority of people in the United States would tolerate much more of our too long involvement in Afghanistan: we - like Alexander the Great - finally came to realize that we would not conquer their people. I, for one, don't see how we can do anything immediate and substantive in Ukraine or with Russia. We've shown that our "red lines in the sand" are attached to invitations to nations who aren't our friends to keep on doing what you're doing while our Fearless Leader(s) mumble vague non-threats.
