The Saudi status-quo are probably quite happy for the American troops to remain there because they're good for business.

well ive read and heard quite a bit stating that one reason for anti americanism is troops being stationed in the holy land, Ive heard its one of AQ's pledges to remove them (which points to at least the more extreme elements being upset at it)

local buisnessmen who make profit from the troops im sure would love them to stay

but that this country is a potential danger for the US and the western world.

i would agree, but i don't see how having troops inside the country makes it less of a danger
