quoted: This is why we fight. Primarily, of course, to protect ourselves from the immediate threat of terrorist carnage, but also because we know that extending the embrace of a civilization that liberates everyone makes us all safer.

Every death is an unspeakable tragedy. It's right that each time a soldier is killed in action we ask why. Was it really worth it?

The right response to the loss of brave souls such as Corporal Sarah Bryant, the first British woman to die in Afghanistan, is not an immediate call for retreat. It is, first of all, pride; a great, deep conviction that it is on such sacrifice that our own freedoms have always rested. Then, defiance. How foolish is the enemy that it might think our grief is really some prelude to their victory? Finally, confidence. We are prevailing in this struggle. We know it. And everywhere: in Afghanistan, in Iraq, and among Muslims around the world, the enemy knows it too.
