Hillary Clinton, Barack Obama and John Edwards have suggested that there is little difference among us on Iraq. This is not true: I am the only leading Democratic candidate committed to getting all our troops out and doing so quickly.

In the most recent debate, I asked the other candidates how many troops they would leave in Iraq and for what purposes. I got no answers. The American people need answers. If we elect a president who thinks that troops should stay in Iraq for years, they will stay for years -- a tragic mistake.

Clinton, Obama and Edwards reflect the inside-the-Beltway thinking that a complete withdrawal of all American forces somehow would be "irresponsible." On the contrary, the facts suggest that a rapid, complete withdrawal -- not a drawn-out, Vietnam-like process -- would be the most responsible and effective course of action.

Those who think we need to keep troops in Iraq misunderstand the Middle East. I have met and negotiated successfully with many regional leaders, including Saddam Hussein. I am convinced that only a complete withdrawal can sufficiently shift the politics of Iraq and its neighbors to break the deadlock that has been killing so many people for so long.

Our troops have done everything they were asked to do with courage and professionalism, but they cannot win someone else's civil war. So long as American troops are in Iraq, reconciliation among Iraqi factions is postponed. Leaving forces there enables the Iraqis to delay taking the necessary steps to end the violence. And it prevents us from using diplomacy to bring in other nations to help stabilize and rebuild the country.

The presence of American forces in Iraq weakens us in the war against al-Qaeda. It endows the anti-American propaganda of those who portray us as occupiers plundering Iraq's oil and repressing Muslims. The day we leave, this myth collapses, and the Iraqis will drive foreign jihadists out of their country. Our departure would also enable us to focus on defeating the terrorists who attacked us on Sept. 11, those headquartered along the Pakistan-Afghanistan border -- not in Iraq.

Logistically, it would be possible to withdraw in six to eight months. We moved as many as 240,000 troops into and out of Iraq through Kuwait in as little as a three-month period during major troop rotations. After the Persian Gulf War, we redeployed nearly a half-million troops in a few months. We could redeploy even faster if we negotiated with the Turks to open a route out through Turkey.

As our withdrawal begins, we will gain diplomatic leverage. Iraqis will start seeing us as brokers, not occupiers. Iraq's neighbors will face the reality that if they don't help with stabilization, they will face the consequences of Iraq's collapse -- including even greater refugee flows over their borders and possible war.

The United States can facilitate Iraqi reconciliation and regional cooperation by holding a conference similar to that which brought peace to Bosnia. We will need regional security negotiations among all of Iraq's neighbors and discussions of donations from wealthy nations -- including oil-rich Muslim countries -- to help rebuild Iraq. None of this can happen until we remove the biggest obstacle to diplomacy: the presence of U.S. forces in Iraq.

My plan is realistic because:

? It is less risky. Leaving forces behind leaves them vulnerable. Would we need another surge to protect them?
