American has been known to stick its nose where it doesn't belong and I feel this might be another case in which that's exercised. Obama might invoke the Truman Doctrine to help set up a democracy in Libya. Especially with next year being an election year, Obama needs to be careful of what steps he takes so that not too many potential voters are offended.
One argument for not stepping in in Libya is the potential for more conflict. Obama is pulling troops out of Iraq, but does it help any to move them straight into Libya? Kadafi still has supporters in Libya, of course. So what would stop them from protesting America's aid to the framers of their constitution.
On the other hand, by creating an ally with Libya could be very instrumental in the acquisition of petroleum, which is abundant in Libya. It goes without saying that that would be a PR win for Obama.
I feel that America will have its hand in the formation of the Libya constitution in one way or another, but I also feel that that will lead to more tension in the middle east, as we are already seen as an enemy. Even though Libyan officials say that they want an Islamic government do you think that's actually how it'll turn out?
