An excerpt from "War Is a Force That Gives Us Meaning," by Chris Hedges. Used by permission from Public Affairs Books.

The enduring attraction of war is this: Even with its destruction and carnage it can give us what we long for in life. It can give us purpose, meaning, a reason for living. Only when we are in the midst of conflict does the shallowness and vapidness of much of our lives become apparent. Trivia dominates our conversations and increasingly our airwaves. And war is an enticing elixir. It gives us resolve, a cause. It allows us to be noble. And those who have the least meaning in their lives, the impoverished refugees in Gaza, the disenfranchised North African immigrants in France, even the legions of young who live in the splendid indolence and safety of the industrialized world, are all susceptible to war's appeal.

Those who make war do so for many reasons, although many of these motives are never acknowledged publicly.

The Palestinian uprising was not just about throwing the Israelis out of Gaza and the West Bank, but also about crushing the urban elite, the shop owners and businessmen, in East Jerusalem and Gaza City. The "strikes" organized by the shabab, the young men who fueled the uprising from the refugee camps, hurt the Palestinian community far more than they hurt the Israelis.

In Bosnia it was the same, the anger turned against a Communist hierarchy that kept for itself the privileges and perks of power even as power slipped from their hands in the decaying state. There is little that angers the disenfranchised more than those who fail to exercise power yet reap powerful rewards. Despots can be understood, even tolerated, but parasites rarely last long.

War is a crusade. President George W. Bush is not shy about warning other nations that they stand with the United States in the war on terrorism or will be counted with those that defy us. 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 neverending.

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. "We go forward," President Bush assures us, "to defend freedom and all that is good and just in the world."

The patriotic bunting and American flags that proliferated in the wake of the attacks on the World Trade Center and the Pentagon were our support for the war mounted against the "axis of evil." Elected officials, celebrities and news anchors lined up to be counted. On Friday, September 14, three days after the attacks, Congress granted the President the right to "use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks." The resolution was passed unanimously by the Senate. 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."

When we ingest the anodyne of war we feel what those we strive to destroy feel, including the Islamic fundamentalists who are painted as alien, barbaric, and uncivilized. It is the same narcotic. I partook of it for many years.

And like every recovering addict there is a part of me that remains nostalgic for war's simplicity and high, even as I cope with the scars it has left behind, mourn the deaths of those I worked with, and struggle with the bestiality I would have been better off not witnessing. There is a part of me--maybe it is a part of many of us--that decided at certain moments that I would rather die like this than go back to the routine of life. The chance to exist for an intense and overpowering moment, even if it meant certain oblivion, seemed worth it in the midst of war--and very stupid once the war ended.

Many of us, restless and unfulfilled, see no supreme worth in our lives. We want more out of life. And war, at least, gives a sense that we can rise above our smallness and divisiveness. The weeks after the September 11 attacks saw New York City, with some reluctance, slip back to normal. One felt the same nostalgia.

The attacks on the World Trade Center illustrate that those who oppose us, rather than coming from another moral universe, have been schooled well in modern warfare. The dramatic explosions, the fireballs, the victims plummeting to their deaths, the collapse of the towers in Manhattan, were straight out of Hollywood.

Where else, but from the industrialized world, did the suicide hijackers learn that huge explosions and death above a city skyline are a peculiar and effective form of communication? They have mastered the language. They understand that the use of disproportionate violence against innocents is a way to make a statement. We leave the same calling cards.
