It would be far better to spend $100 billion per year granting them political asylum and paying for their transport and relocation to the US than invading their countries and caressing them with our freedom bombs.
Or you could come up thousands of other ways to spend $100 billion all of which would be almost infinitely better than invading their countries and caressing them with our freedom bombs if we cared about the women and children of the world.
So when an asshole like Rick Stengel suggests we must stay in Afghanistan otherwise more girls will be mutilated even though we're currently in Afghanistan and poor girls are still being tragically mutilated, I don't think that's the real reason he thinks we should be there.
