This too is a jihad. Yet we Americans find ourselves in the dangerous position of going to war not against a state but against a phantom. The jihad we have embarked upon is targeting an elusive and protean enemy. The battle we have begun is never-ending. But it may be too late to wind back the heady rhetoric. We have embarked on a campaign as quixotic as the one mounted to destroy us.

Battling evil, cruelty, and injustice allows us to retain our identity, a sense of meaning, and ultimately our freedom.

I have seen children shot in El Salvador, Algeria, Guatemala, Sarajevo, but I have never before watched soldiers entice children like mice into a trap and murder them for sport.

There was in the House only one dissenting vote, from Barbara J. Lee, a Democrat from California, who warned that military action could not guarantee the safety of the country and that 'as we act, let us not become the evil we deplore.

I think most generations tend to learn the lesson of war the hard way. There is a deep attraction to the empowerment. Freud is right: societies either become locked in a collective embrace of Eros, as individuals do, or a collective embrace of Thanatos, the death instinct. They swing between the two. The notion that societies are naturally prone toward self-preservation is wrong. Self-annihilation can be deeply addictive, intoxicating, enticing. So I take a darker view of human nature, that war is probably always going to be with us. I think history bears me out.

And let's not forget that internally, we are, like all dying empires, being hollowed out from the inside in terms of infrastructure. I live near Philly, I live in Princeton. The school system is shattered with closings and layoffs. Libraries are being shuttered. Head Start is being cut back. Unemployment benefits are not being extended. You know, we've reached a point of both physical and emotional exhaustion.

What kind of a world are we going to leave the next generation? I, at least, want my children to look back and say, "My daddy was being arrested at the White House fence and booed off commencement stages. He was trying."
