US Vice President Dick Cheney is reaching out to moderate Arab leaders for help in bringing stability to Iraq, a mission that will include pleas for postwar support for minority party Sunnis. Cheney departs Tuesday on a weeklong mission to the Middle East, right after a visit to the region by Secretary of State Condoleezza Rice. While Rice's trip had a wide-ranging agenda that included other tensions in the region, administration officials said Cheney would focus largely on the next steps in Iraq. Cheney's first stop will be Abu Dhabi in the United Arab Emirates. Other announced stops include Saudi Arabia, Egypt and Jordan. Cheney also will visit the aircraft carrier John C. Stennis in the Persian Gulf.
