A died in the wool isolationist, who is negotiating trade deals, negotiating peace settlements, attacking Syria & ISIS, standing up to Russia with sanctions, fighting Russian mercs, putting troops in Poland, and demanding that NATO require all of its member countries honor their commitments to beef up the NATO forces, beefing up the US military...that's just off the top of my head.
I'd be good if he were more of an isolationist. But, let's not fool ourselves about what he is.
