Two former secretaries of state urged President George W. Bush on Wednesday to go beyond a planned buildup of US forces in Iraq to develop a comprehensive strategy for the Middle East. They called for wide ranging-talks with Iraq's neighbors, including Iran and Syria, and increased autonomy for clashing Iraqi groups. Former Secretary Henry A. Kissinger said the planned buildup of 21,500 US troops appears to be "the best way to get the maneuvering room to the changes in deployment and strategy that will be required by the evolving situation." "I think the focus has been on the surge," he testified. "My focus is the other way around: to explain the surge in terms of the strategy to which way we should go."
