Why pull out of Iraq? We just got there. Why don't we take a FIFO (First in, First Out) approach. Lets pull out all out troops from Europe, because those troops have been there the longest. We can send half home and half to Iraq. Next lets pull all troops our of South Korea, we can send half home and half to Iraq. We can post some subs to keep an nuclear eye on North Korea. Next lets pull troops out of Vietnam (I don't really think we have very many there, but I am just mentioning it here for completeness.)
Once we have removed troops from all the places they were before Iraq and relocated them to Iraq, I would support pulling out of Iraq.
