This is probably my favorite line from the president’s address last night: “For America, there will be no going back to the era before September the 11th, 2001 — to false comfort in a dangerous world. 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.” It reminded me of something Kate O’Beirne used to say, when we were debating whether there should be a new Department of Homeland Security: “I already have a Secretary of Homeland Security. His name is Don Rumsfeld.”
