Two problems with what you're saying. 1. Foreign aid is less than 1 percent of the budget.. It isn't like getting rid of it would solve any major domestic problems. Unless you're talking about cutting defense spending, but I don't think you are. Correct me if I'm wrong. 2. It's easy to talk about problems caused by our policies. I'm not going to refute the ones you bring up because you're right about them. But you also have to consider what problems the alternative would cause. And the alternative didn't work out well; the last time we were isolationist WWII happened. And we vowed not to make that mistake again. I don't think of foreign spending as charity but as insurance against a world that turns its back on our ideals.
