Is Lebanon Unique?

Anyone with half a brain (which excludes the current administration in the White House) knows that Americans will continue to be shot at and killed in Iraq as they are seen as an occupying force. The only solution is to do what should have been done in the first place - send international troops, led by troops from Muslin countries, into Iraq. Why is it that Bush agrees on the need to send in international troops to secure the peace in Lebanon days after hostilities end, but refuses to do the same thing three and a half years (and thousands of lives) after his disastrous folly in Iraq?! Gee, could it be because Lebanon doesn't sit on a huge pool of oil and doesn't have a ton of "projects" that his Halliburton buddies can make billions a year on?
