My guess is Foreign Aid is unconstitutional. Especially of the variety that the country that receives the aid, isn't obligated to pay the money back.
Aiding a country like Jordan, that would love to destroy the United States, is nothing short of insane. This is bad from both an economic and national security standpoint. This doesn't even touch on the most important implication of this decision, the biblical implication. Though the Democrats are much worse, G.W. Bush continues to act like a Liberal.
