NATO on the Cheap
U.S. Defense Secretary Robert Gates, left, and former NATO Secretary General Jaap de Hoop Scheffer during a Security and Defense Agenda event Friday at the Biblioteque Solvay in Brussels. In his final policy speech as Pentagon chief, Gates questioned the viability of NATO, saying its members' penny-pinching and lack of political will could hasten the end of U.S. support. The North Atlantic Treaty Organization was formed in 1949 as a U.S.-led bulwark against Soviet aggression, but in the post-Cold War era it has struggled to find a purpose. (AP Photo)
