While that is in large part, been no hidden agenda, it also is costing the lives of American GI's, since control of foreign oils, whether admittedly or not, in roundabout subtle ways, is still the reason more often than not, we find our military overseas.
Total independance of the U.S. from foreign oil is still key to obtaining whatever level of peace is possible. If our American ingenuity would only start mass producing other forms of energy, we would probably even find other countries following suit more closely, thereby minimimizing on a broader scale, the dependancy and wars over oil.
