     The nervous-looking young man had waited for a few moments outside the jeweler's before he got enough

courage to enter. He was warmly greeted by a young assistant. James felt a rush of blood to his face as he

explained he would be bringing in his future wife to choose a birthday present. The assistant listened carefully

and told him he'd better buy a necklace (项链). He wasn't used to buying jewelry and was a little worried about

overspending, because he was not very rich. After some discussion as to a reasonable price and the type, the

assistant showed him dozens of necklaces and helped him to choose. At last James chose one and left the shop

promising to return at five o'clock. Half an hour later than planned, James did return to the shop with his future

wife, Laura. The assistant acted as if she had never seen him before. When she was asked to show them some

necklaces, she first brought out some inexpensive ones for them to choose, and then gave them the ones she

had prepared. A choice was soon made and they went away satisfactorily. Later James would certainly come

back to buy what he wanted when he got married.

In War Made Easy Norman Solomon demolishes the myth of all independent American press zealously guarding sacred values of free expression. Although strictly focusing on the shameless history of media cheerleading for the principal post World War’ Ⅱ American wars, invasions, and interventions, he calls into question the entire concept of the press as some kind of institutional counterforce to government and corporate power.

Many of the examples compiled in this impeccably documented historical review will be familiar to readers who follow the news on the Internet. But such examples achieve flesh impact because of the way Solomon has organized and analyzed them. Each chapter is devoted to a single warhawk argument ( " America Is a Fair and Noble Superpower, " " Opposing the War Means Siding with the Enemy, " "Our Soldiers Are Heroes, Theirs Are Inhuman " ), illustrated with historical examples from conflicts in the Dominican Republic, E1 Salvador, Vietnam, Grenada, Panama, Kosovo, both Iraq wars, and others in which the media were almost universally enthusiastic accomplices.

The book should really be subtitled " War reporting doesn’t just suck, it kills. " It makes you feel like demanding a special war crimes tribunal for corporate media executives and owners who joined the roll-up to " shock and awe " as non-uniformed psywar ops. To be sure, this would raise the issue of whether or not following orders might suffice for the defense of obedient slaves such as Mary McGrory and Richard Cohen, who performed above and beyond the call of duty. " He persuaded me, " McGrory gushed the morning after Colin Powell addressed a plenary session of the United Nations on February 5,2003, declaring that Iraq had weapons of mass destruction. " The cumulative effect was stunning." In the same Washington Post edition, Cohen wrote.

The evidence he presented to the United Nations—some of it circumstantial, some of it absolutely bone-chilling in its detail—had to prove to anyone that Iraq not only hasn’t accounted for its weapons of mass destruction but without a doubt still retains them. Only a fool could conclude otherwise.

Solomon demonstrates how this kind of peppy prewar warm-up degenerates into drooling and heavy breathing once the killing begins. As if observing a heavy metal computer game, the pornographers of death concentrate on the exquisite craftsmanship and visual design of the murder machines, and the magnificence of the fiery explosions they produce.
