Productive lives of service and charity?

There it is:

As we fight the war on terror in Iraq and on other fronts, we must keep in mind the nature of the enemy. No act of America explains terrorist violence, and no concession of America could appease it. The terrorists who attacked our country on September the 11th, 2001 were not protesting our policies. They were protesting our existence. Some say that by fighting the terrorists abroad since September the 11th, we only stir up a hornet's nest. But the terrorists who struck that day were stirred up already. (Applause.) If America were not fighting terrorists in Iraq, and Afghanistan, and elsewhere, what would these thousands of killers do, suddenly begin leading productive lives of service and charity? (Laughter.) Would the terrorists who beheaded an American on camera just be quiet, peaceful citizens if America had not liberated Iraq? We are dealing here with killers who have made the death of Americans the calling of their lives. And America has made a decision about these terrorists: Instead of waiting for them to strike again in our midst, we will take this fight to the enemy. (Applause.)
