Guys, I know you love to rag on the liberals, but I prefer to target them accurately, not make up FUD on them.
To be blunt, I get the idea that he views that some aid money will end up in the hands of terrorists like how it's impossible to eliminate all fraud, waste, and abuse of federal monies.
We still need a military, after all, and cutting all funding because a little would be lost in FW&A would mean that we wouldn't have a military.
So really, what one needs to do is put enough controls on the money that the amount that leaks to terrorists is small enough that the benefits of the aid still exceeds that of the amount the terrorists get. Hell, keep track of the money and use any identified terrorist transfers to help with the next wave of drone strikes.
