Since 9/11, I've spent way too much of my time in places like Afghanistan, Pakistan, Yemen, Syria and Libya, and the U.S. approach in dealing with those security problems has been to rely on the military toolbox and blow things up. We've seen that that's a very expensive toolbox, and I think we've underinvested in the women's empowerment toolbox and the education toolbox, which are also imperfect but are also powerful tools to bring about change.
