To accept your premise is to give lie to the administration's stated purpose for being there in the first place.
No. I compare them to the French resistance, Basques, Italians, Slovenes etc. that came here or Canada after WW2. There were a lot of bombings and asassinations of those people after that war was over by still-NAZI sympathizers. A different civilization with the same end result.
Wait until a treaty gets hammered out with a status-of-forces agreement. We will have guest bases there as part of Iraqi bases. Their military will come here for advanced or special training or vacation as guests also. Our Congress and their Parliament will be talking/meeting with each other after the diplomats lay out the points and needs of both countries. That will take time.
A Treaty is not a screw the U.S. Citizens amnesty bill.
