Development and diplomacy protect our nation by addressing the root causes of terrorism and conflict. But it's not just about security. By building new markets overseas for American products, the International Affairs Budget creates jobs and boosts the economy here at home.

Remember back then we thought about al Qaeda in Afghanistan and Pakistan and a few other places? well, we've seen al Qaeda metastasize. It is now a global scourge. And you have the ascendancy of ISIL.
