I'll vote for Paul in the primaries, but I'm also being realistic. My support for him is because he's moving the GOP back to its traditional roots and he's restoring the old Reagan coalition. Now his foreign policy does make me nervous though. I don't think we should pull out immediately from Iraq.
Regardless of how unpopular the war is, until Iraq gets back on an even keel we need to stay there and clean up our mess.
My step-son just returned from his third tour over there with the Marines. He doesn’t want to go back and we here at home don’t want him over there either so we need to let the Iraqis run their own country. If they turn it back into another tyrannous hell-hole... Well, it’s their hole.
Don't worry too much about that. A lot can change in another year's time.
It's impossible to truly move back to the traditional roots (if by that you mean early 20th century roots) of the GOP without adopting a non-interventionist foreign policy. While there have been hawks in the Republican past (see Abraham Lincoln for one) generally the stance of much of the party from the early 1900's up until Eisenhower (who deviated in a limited way) and further until George H. W. Bush (who certainly deviated from that principle in a more egregious way) was non-interventionist.
I don't fear what will happen to us if we pull out immediately. Think about it. These guys have been fighting amongst each other for centuries and beyond. If we remove ourselves out from the middle of their endless conflicts, then they will most likely begin (as they always have done) to fight amongst themselves again---thereby leaving them little time or resources to fight against us and insufficient motive for doing so.
And it will leave us with more time, manpower and resources to shore up our defenses here at home (including reversing this sometimes insipid trend of domestic base closures which have happened under both Clinton and George W. Bush). A real, formidable national defense and less incentive for enemies to attack us---sounds like the plan for me.
