Murderers are not martyrs. Targeting civilians is immoral, whatever the excuse. Terrorists have declared war on civilization, and states like Iran, Iraq and Syria are inspiring and financing a culture of political murder and suicide bombing. The president has declared war on terrorism. It's a war unlike any other America has ever fought-not only in the nature of the battle and the weapons and tactics employed, which will undoubtedly change from place to place, but in this conflict, the battlefield is but one front of many. . . .
The question boils down to this: How long will we keep doing what we're doing to protect the American people from attack from weapons of mass destruction and from terrorism of the type we witnessed on Sept. 11? And the answer is: as long as it takes.
