"Former U.S. Secretary of State Henry Kissinger, who helped engineer the U.S. withdrawal from Vietnam, said Sunday the problems in Iraq are more complex than that conflict, and military victory is no longer possible," reports the Associated Press. "The faceless, ubiquitous nature of Iraq's insurgency, as well as the religious divide between Shiite and Sunni rivals, makes negotiating peace more complex, he said. 'It is a more complicated problem,' Kissinger said. 'The Vietnam War involved states, and you could negotiate with leaders who controlled a defined area.'... Kissinger said the best way forward is to reconcile the differences between Iraq's warring sects with help from other countries. He applauded efforts to host an international conference bringing together the permanent members of the U.N. Security Council and Iraq's neighbors -- including Iran, Washington's longtime rival in the region."
