The U.S. hosted world leaders over the weekend at the G-8 summit at Camp David and the ongoing NATO summit in Chicago, President Obama's hometown. Two intertwined issues topped the agendas - Europe's economic turmoil and the war in Afghanistan. As the E.U. continues to struggle with financial crises and political upheaval at home, there's little appetite for looking outward. Who will pay the annual $4 billion bill for security in Afghanistan after U.S. and NATO troops withdraw remains an open question. Diane and her guests discuss the role of the U.S. and its allies in Afghanistan and the future of shared security.
