I suspect the terrorists who planned this act thought far enough in advance to grasp the political pressures that would be brought to bear on President Bush and the American Congress to respond in a way which would not appear "weak."
Our strength does not lie in our military power, but in our ability to rally the world around this vision: a vision of a world without lawless terrorism. But this vision depends on leading by example, not sheer power.
A wise man said, "...a man who rules his own spirit is stronger than a man who rules a city." I would add, "...a man who influences leaders to agreee, and act, with him, is stronger than a man who rules nations."
