I’ve been in favor of moving American troops to Kuwait and Kurdistan and letting the various Iraqi factions settle itself, with American troops playing Spoiler for our own interests. Upon further thought I’m not so sure.
Kuwait isn’t really a factor, but Kurdistan is. Assuming that the Kurds do secede (which seems likely) we would be the guarantor of last resort for an ethnically homogeneous enclave, much like we are with Israel. While supporting the Israelis is perhaps the right thing to do, it’s doubtful that the relationship is worthwhile on a cost benefit basis. That raises the question, do we really need another exposed ally with little to offer surrounded by hostile countries? Supporting the Kurds would alienate the surrounding countries and be a considerable financial and troop expense.
Then again, it does put another outpost of democracy and freedom (for the region) in the area and the second Israel isn’t the same as the first.
