The terrorists made a huge blunder, and they've just given us the momentum and a reason to hit them harder. They did not break our resolve through this act; they strengthened it. Now we've got a shot in the arm, moving from fighting in principle to fighting in principled anger.
This was a concrete example as to why the War on Terror is right and necessary. I hope we hit them so hard that those who live through the coming bombing can't see straight.
Don't mess with America.
