Here's what that soldier with a stellar career has to say (go read the whole thing):
If the Democrats truly want to succeed in forcing to begin withdrawing from Iraq, the first step is to redefine "supporting the troops" as withdrawing them, citing the mass of accumulating evidence of the psychological as well as the physical damage that the president is forcing them to endure because he did not raise adequate forces. Both Democrats and Republicans in Congress could confirm this evidence and lay the blame for "not supporting the troops" where it really belongs – on the president. And they could rightly claim to the public that they are supporting the troops by cutting off the funds that he uses to keep U.S. forces in Iraq.
The public is ahead of the both branches of government in grasping this reality, but political leaders and opinion makers in the media must give them greater voice.
Congress clearly and indisputably has two powers over the executive: the power of the purse and the power to impeach. Instead of using either, members of congress are wasting their time discussing feckless measures like a bill that "de-authorizes the war in Iraq." That is toothless unless it is matched by a cut-off of funds.
The president is strongly motivated to string out the war until he leaves office, in order to avoid taking responsibility for the defeat he has caused and persisted in making greater each year for more than three years.
To force him to begin a withdrawal before then, the first step should be to rally the public by providing an honest and candid definition of what "supporting the troops" really means and pointing out who is and who is not supporting our troops at war. The next step should be a flat refusal to appropriate money for to be used in Iraq for anything but withdrawal operations with a clear deadline for completion.
The final step should be to put that president on notice that if ignores this legislative action and tries to extort Congress into providing funds by keeping U.S. forces in peril, impeachment proceeding will proceed in the House of Representatives. Such presidential behavior surely would constitute the "high crime" of squandering the lives of soldiers and Marines for his own personal interest.
