Out here in Anbar Province, al Qaeda did what religion-driven extremists always do eventually — they over-reached, setting the bar so high that nonfanatics couldn’t measure up (nor did they want to). The terrorists responded with a campaign of slaughter against their fellow Muslims.

Now the Sunni Arabs who were fighting so bitterly against us are fighting beside us to destroy al Qaeda in Iraq. And the terrorists are going down.

Out here in Anbar Province — long the most troubled in Iraq — the change has come so swiftly and thoroughly that it’s dazzling. Marines who were under fire routinely just months ago are now directing their former enemies in battle.

Although this trend has been reported, our battlefield leaders here agree that the magnitude of the shift hasn’t registered back home: Al Qaeda is on the verge of a humiliating, devastating strategic defeat – rejected by their fellow Sunni Muslims.

If we don’t quit, this will not only be a huge practical win – it’ll be the information victory we’ve been aching for.

No matter what the Middle Eastern media might say, everyone in the Arab and greater Sunni Muslim world will know that al Qaeda was driven out of Iraq by a combination of Muslims and Americans.

Think that would help al Qaeda’s recruitment efforts? Even now, the terrorists have to resort to lies about their prospective missions to gain recruits.

With the sixth anniversary of 9/11 approaching, how dare we throw away so great a potential victory over those who attacked our country?
