A 22-year-old Marine on why he wants Congress to bring the troops home.

If there was one constituency President Bush could count on to back the war in Iraq through the past four years, it was members of the military. Now, their support is also ebbing. A poll conducted recently by Army Times, a commercial publication, showed only 35 percent of service members approve of the way Bush is handling the war, down from 63 percent in 2004. When asked if success in Iraq was likely, 50 percent said yes, compared to 83 percent two years ago.

In a sign of the erosion, more than 1,000 soldiers will urge their congressmen in a written appeal this week to "support the prompt withdrawal" of all American forces from Iraq. "Staying in Iraq will not work and is not worth the price," the statement says. Anti-war appeals are common these days but this one is different: all the signatories are active duty soldiers and some have served in Iraq.

One of the appeal's organizers is Liam Madden, a 22-year-old Marine Corp. Sergeant now based Quantico, VA. He spoke to NEWSWEEK's Dan Ephron.
