Congressional Democrats searching for a message that will resonate on the Iraq war are preparing an argument that getting troops out of the conflict is the only way to rebuild a spent military.

It’s a less ambitious argument than the “Out-of-Iraq now” proposals put forward last year, but House Speaker Nancy Pelosi (D-Calif.) and other top Democrats believe it will allow the party to criticize the war without being seen as criticizing those fighting it. It could also help Democrats to portray themselves as protecting the military and national security.

“This is about America’s security,” said Rep. Joe Sestak (D-Pa.). “We have an Army that can’t deploy anywhere else in the world.”

Or, as a staffer put it, “You can’t rebuild an engine while you’re driving along at 60 miles per hour.”

A Democratic aide noted that numerous generals have complained that the Iraq war is stretching the military too thin. “Who can argue with that?” the aide said. “You’re not blaming the military for anything.”

The new angle on Iraq reflects sentiments among Democratic leaders that they became too focused on opposing Bush’s “surge” and then saw their push for withdrawal falter when the surge was viewed as a military success. At the same time, the new strategy is not necessarily in sync with other efforts on Iraq.

The Congressional Progressive Caucus, which overlaps with the Out-of-Iraq caucus, last week introduced legislation calling for withdrawal of troops within a year. Anti-war groups are trying to link the Iraq war to the economic slowdown in what they call an “Iraq/recession” campaign.

The Senate last week debated a plan to withdraw troops within 120 days, and Republicans seemed more eager to debate it than did Democrats. President Bush has backed off plans to draw troop levels down to pre-surge levels, with little public backlash.

Leadership aides say the exact legislative strategy for linking readiness to withdrawal hasn’t been developed as Democrats and their allies build their case. But Democrats will use the budget battle that begins this week to showcase their differences with President Bush on veterans’ healthcare and military readiness.

Another potential legislative vehicle is a military readiness resolution sponsored by Reps. Neil Abercrombie (D-Hawaii) and Solomon Ortiz (D-Texas), both Armed Services subcommittee chairmen. The resolution lists a host of shortfalls in the armed services and states,  “Congress should restore and maintain the ground forces.”

The resolution, which makes little mention of Iraq, has been repeatedly discussed at the ad hoc Iraq strategy task force run by House Caucus Vice Chairman John Larson (D-Conn.).

Abercrombie said that in caucus meetings the resolution has been discussed as “the central focus of our approach on Iraq.”

Republicans say that they’re equally committed to making sure the military has what it needs, but that the military doesn’t need to withdraw from Iraq to have those needs met.

“House Democrats’ Iraq policy is like a broken Magic 8-Ball,” said Michael Steel, spokesman for House Minority Leader John Boehner (R-Ohio). “No matter what question you ask, the answer is always ‘Retreat.’ ”

The issue of “military readiness” is not new. Rep. John Murtha (D-Pa.) complained that “the Army is broken” when he came out against the war in 2005.
