The money pit

So there’s this dude, right? And he’s from this place called Yemen, ‘kay? And he tries to blow an airplane by lighting his explosive underwear on fire. This crackerjack plan doesn’t quite work out.

If you’re the United States, what’s the appropriate response?

Did you say give Yemen $1.2 billion in military training and aid?

I seem to recall something about a concept called “diminishing returns”. I don’t know why it springs to mind. Hmm…oh well.
