The money will funnel back into the US eventually anyways. Unless you have some reason to prefer giving defense contractors the money, the money might as well go to whatever middle eastern people like to buy from the US. The advantage of this scheme is that fewer lives need to be lost, the regions in question can become more stable and productive, and US interests are better promoted.
