Cheney stopped short of joining those Republicans who have questioned the patriotism and courage of Rep. John Murtha, D-Pa., calling him "a good man, a Marine, a patriot." Cheney's subdued comments about Murtha followed those of President Bush and Defense Secretary Donald H. Rumsfeld.

As to proposals for a rapid pullout of U.S. troops, Cheney said, "It is a dangerous illusion to suppose that another retreat by the civilized world would satisfy the appetite of the terrorists and get them to leave us alone." Nearly 160,000 U.S. troops remain in Iraq.
