The Discerning Texan

I've just spent 10 days traveling in the Middle East and speaking to leaders there, all of which has made one thing clearer to me than ever: While we are naturally focused on Iraq, a larger war is emerging. On one side are extremists and terrorists led and sponsored by Iran, on the other moderates and democrats supported by the United States. Iraq is the most deadly battlefield on which that conflict is being fought. How we end the struggle there will affect not only the region but the worldwide war against the extremists who attacked us on Sept. 11, 2001.

Because of the bravery of many Iraqi and coalition military personnel and the recent coming together of moderate political forces in Baghdad, the war is winnable. We and our Iraqi allies must do what is necessary to win it.

The American people are justifiably frustrated by the lack of progress, and the price paid by our heroic troops and their families has been heavy. But what is needed now, especially in Washington and Baghdad, is not despair but decisive action -- and soon.

The most pressing problem we face in Iraq is not an absence of Iraqi political will or American diplomatic initiative, both of which are increasing and improving; it is a lack of basic security. As long as insurgents and death squads terrorize Baghdad, Iraq's nascent democratic institutions cannot be expected to function, much less win the trust of the people. The fear created by gang murders and mass abductions ensures that power will continue to flow to the very thugs and extremists who have the least interest in peace and reconciliation.

This bloodshed, moreover, is not the inevitable product of ancient hatreds. It is the predictable consequence of a failure to ensure basic security and, equally important, of a conscious strategy by al-Qaeda and Iran, which have systematically aimed to undermine Iraq's fragile political center. By ruthlessly attacking the Shiites in particular over the past three years, al-Qaeda has sought to provoke precisely the dynamic of reciprocal violence that threatens to consume the country.

On this point, let there be no doubt: If Iraq descends into full-scale civil war, it will be a tremendous battlefield victory for al-Qaeda and Iran. Iraq is the central front in the global and regional war against Islamic extremism.

To turn around the crisis we need to send more American troops while we also train more Iraqi troops and strengthen the moderate political forces in the national government. After speaking with our military commanders and soldiers there, I strongly believe that additional U.S. troops must be deployed to Baghdad and Anbar province -- an increase that will at last allow us to establish security throughout the Iraqi capital, hold critical central neighborhoods in the city, clamp down on the insurgency and defeat al-Qaeda in that province.
