I can see him very much saying (either privately or publicly) that those conditions for them to return home are to remove the threat of why they left, and to help them get started on the rebuild....after that, they are on their own.

Remember, he also said multiple times about our friends, allies, neighbors to "pay their fair share." This also means for them to take care of their citizens. Many Americans are upset that we provide huge degrees of foreign aid to countries, who then turn right around and either bad-mouth us or mouth off in some manner. It would be much akin to you giving someone in need both rent and food money, only for them to talk trash about you. One often counters that the foreign aid we give increases security (by decreasing poverty/crime/so on)...however the secondary counter is then to say, "No. Our military, bombs, drones, and everything else we have will give us our security."

I wouldn't say that we are xenophobic or isolationist, but we are definitely more of a "homebody" then most nations.
