A leading Republican senator and prospective presidential candidate said Sunday that the war in Iraq has destabilized the Middle East and is looking more like the Vietnam conflict from a generation ago.
Nebraska Sen. Chuck Hagel, who received two Purple Hearts and other military honors for his service in Vietnam, reiterated his position that the United States needs to develop a strategy to leave Iraq. Hagel scoffed at the idea that U.S. troops could be in Iraq four years from now at levels above 100,000, a contingency for which the Pentagon is preparing.

Hagel said "stay the course" is not a policy. "By any standard, when you analyze 2 1/2 years in Iraq ... we're not winning," he said.

President Bush was preparing for separate speeches this week to reaffirm his plan to help Iraq train its security forces while its leaders build a democratic government. In his weekly Saturday radio address, Bush said the fighting there protected Americans at home.

Polls show the public growing more skeptical about Bush's handling of the war.
