A recent political article in a Detroit newspaper was about the politicians stance on foreign policy, especially Iraq and Iran. In the case of Iraq, I've been surprised to hear that the Surge may have been successful and caused the country to become more stable than it has been a couple years into the war. It makes me think that pulling all the troops out suddenly might not be a good thing.
Of course, I always have felt that pulling out prematurely was a bad thing for both parties.
As for Iran, one of the things that scares me the most about radical right wing Christianity is reflected in an article I read in a right wing christian political magazine. The Editor went on about Iran and stated that the best way to solve the problem with Iran was to invade and conquer and take over Iran and force a new government on them.
As much as I don't like the wackjob that runs Iran right now.... but Conquer? Apparently this editor grew up in the 1600s which would make him not much older than Rush Limbaugh and Larry King. Sure, conquering and killing native civilizations was a viable career back then, but I assume that we've evolved since then. Oh wait... I used the word evolve... the one term those extreme right wingers hate the most.

I would prefer talking, like Obama has suggested, rather than conquering. McCain mentions possible sanctions, but look how good those worked for Iraq. Sure Hussein didn't have any nukes, but his people were starving as well.
