Most of that foreign aid goes to Israel. So you want to cut them off? Unlike the constant "foreign aid is bad" mantra that has been coming from the right since I was a child, much of this money serves a strategic purpose. Israel is essentially a giant air craft carrier right next to the Suez Canal and the Saudi oil fields. South Korea provides a buffer between Japan and China, and is essentially a giant aircraft carrier in the heart of Asia. Aid to South America and Africa is for the most part returned to the US in the form of food purchases, propping up US commodity prices on the one sector where we hold a balance of trade surplus. It's not going to be "40 billion", it will be the usual symbolic pittance it usually is so that hot air windbags can take a load of crap home to their constituents, because a lot of that money really needs to be spent.
