The resurrection of Henry Kissinger was one of the more unusual side stories of the last election, and the former secretary of state seems determined to make good on his newfound popularity. In an op-ed for The Washington Post, Kissinger praises Obama's national security team. Most interesting is his advice to Hillary. "I know of no exception to the principle that secretaries of state are influential if and only if they are perceived as extensions of the president," Kissinger writes. "The Beltway system of leak and innuendo will mercilessly seek to widen any even barely visible split." Clinton's "most immediate challenges are to provide strategic guidance and to reorganize the department so that its implementing capacity matches its extraordinary reporting skill."
