President Barack Obama's promise to end the war in Iraq will be on the agenda Wednesday when the new commander in chief meets with top national security aides and senior commanders, officials said. Obama was summoning his holdover defense secretary, Robert Gates, and the chairman of the Joint Chiefs of Staff, Navy Adm. Mike Mullen, to the White House, along with other members of his National Security Council, to discuss a way ahead in the war, according to two senior military officers. The officers spoke on condition of anonymity, because the White House had not publicly announced the meeting. The war in Afghanistan also was to be discussed, with the commander overseeing both conflicts, Gen. David Petraeus, scheduled to attend. Also scheduled to participate via videoteleconference were Gen. David McKiernan, top commander in Afghanistan, and Gen. Ray Odierno, the top commander in Iraq.
