. . . By now, the Taliban's stronghold in Kandahar had fallen or, more correctly, had been abandoned by the soldiers of the regime. The Taliban retreat from Kandahar was emblematic of the war. None of Afghanistan's cities had been won by force alone. Taliban fighters, after intense bombing, had simply made strategic withdrawals. A number of American officers were now convinced that this was about to happen at Tora Bora, too.

One of them was Brig. Gen. James N. Mattis, the commander of some 4,000 marines who had arrived in the Afghan theater by now. Mattis, along with another officer with whom I spoke, was convinced that with these numbers he could have surrounded and sealed off bin Laden's lair, as well as deployed troops to the most sensitive portions of the largely unpatrolled border with Pakistan. He argued strongly that he should be permitted to proceed to the Tora Bora caves. The general was turned down. An American intelligence official told me that the Bush administration later concluded that the refusal of Centcom to dispatch the marines - along with their failure to commit U.S. ground forces to Afghanistan generally - was the gravest error of the war.

A week or so after General Mattis's request was denied, the turning point in the battle of Tora Bora came. It was Dec. 12. . . . American intelligence officials now believe that some 800 Qaeda fighters escaped Tora Bora that night. Others had already left; still others stayed behind, including bin Laden. "You've got to give him credit," Gary Schroen, a former C.I.A. officer who led the first American paramilitary team into Afghanistan in 2001, told me. "He stayed in Tora Bora until the bitter end." By the time the Afghan militias advanced to the last of the Tora Bora caves, no one of any significance remained: about 20 bedraggled young men were taken prisoner that day, Dec. 17.

On or about Dec. 16, 2001, according to American intelligence estimates, bin Laden left Tora Bora for the last time, accompanied by bodyguards and aides. . . . Tora Bora was the one time after the 9/11 attacks when United States operatives were confident they knew precisely where Osama bin Laden was and could have captured or killed him. Some have argued that it was Washington's last chance; others say that although it will be considerably more difficult now, bin Laden is not beyond our reach. But the stakes are considerably higher than they were nearly four years ago, and terrain and political sensibilities are far more our natural enemies now.

On September 11, remember Tora Bora. Remember that the perpetrators of the great atrocity were cornered and BushCo did nothing. And continue to do nothing:

Q But don't you believe that the threat that bin Laden posed won't truly be eliminated until he is found either dead or alive?

THE PRESIDENT: Well, as I say, we haven't heard much from him. And I wouldn't necessarily say he's at the center of any command structure. And, again, I don't know where he is. I -- I'll repeat what I said. I truly am not that concerned about him. I know he is on the run. I was concerned about him, when he had taken over a country. I was concerned about the fact that he was basically running Afghanistan and calling the shots for the Taliban.

But once we set out the policy and started executing the plan, he became -- we shoved him out more and more on the margins. He has no place to train his al Qaeda killers anymore. And if we -- excuse me for a minute -- and if we find a training camp, we'll take care of it. Either we will or our friends will. That's one of the things -- part of the new phase that's becoming apparent to the American people is that we're working closely with other governments to deny sanctuary, or training, or a place to hide, or a place to raise money.

The problem has always been that the Bush Administration was not concerned about Al Qaida and bin Laden - except when an election approaches. He was not concerned on August 6, 2001. He was not concerned in March 2002. He was "concerned" in the Fall of 2004. He's "concerned" now. Concerned about politics. That's what always has concerned the Bush White House.
