We have learned that terrorist attacks are not caused by the use of strength; they are invited by the perception of weakness. And the surest way to avoid attacks on our own people is to engage the enemy where he lives and plans. We are fighting that enemy in Iraq and Afghanistan today so that we do not meet him again on our own streets, in our own cities.
