The USA is acting on behalf of the Jewish interests within the USA in support of anything Israel wants. Clearly we have all the oil we need, so it's not that. The Arab countries are so far from North America it can't be defense related. No the middle east has been in a constant state of turmoil since the state of Israel was formed. Smart of them to continue to faction the Arabs instead of turning their combined attention on Israel. Money, power and propaganda is not on the Arab side, so to day it's Iran, and  Syria before it was Iraq...ya da ya da ya da.
