United Nations peacekeeping operations are vital to global stability, with over 100,000 troops and police deployed to 15 missions, serving 125 million people across the world. But these missions lack sufficient numbers of well-trained troops and a sustainable political plan to resolve complex mandates.

How can the U.S. use its influence to ensure progress on reforms to make U.N. peacekeeping more effective, cost-efficient, and professional?
