A loss of bipartisanship threatens U.S. foreign policy, outgoing Defense Secretary Robert Gates said on “Fox News Sunday.” Gates said: "When we have been successful in national security and foreign affairs, it has been because there has been bipartisan support. . . . That's what happened through nine presidencies and the Cold War that led to our success, because no major international problem can be solved on one president's watch." When asked what can be done to prevent partisanship from bleeding into foreign policy and national security, Gates responded: "I'm not sure what can be done, quite frankly." He has tried to foster a civil dialogue between the executive branch and the Congress. "When individuals make this effort," Gates said, "they can make headway."
