THE DARK SIDE: The Inside Story of How the War on Terror Turned into a War on American Ideals. By Jane Mayer: Doubleday. 392 pp. $27.50

With the appearance of this very fine book, Hillary Clinton can claim a belated vindication of sorts: A right-wing conspiracy does indeed exist, although she misapprehended its scope and nature. The conspiracy is not vast and does not consist of Clinton-haters. It is small, secretive and made up chiefly of lawyers contemptuous of the Constitution and the rule of law.

In The Dark Side, Jane Mayer, a staff writer for the New Yorker, documents some of the ugliest allegations of wrongdoing charged against the Bush administration. Her achievement lies less in bringing new revelations to light than in weaving into a comprehensive narrative a story revealed elsewhere in bits and pieces. Recast as a series of indictments, the story Mayer tells goes like this: Since embarking upon its global war on terror, the United States has blatantly disregarded the Geneva Conventions. It has imprisoned suspects, including U.S. citizens, without charge, holding them indefinitely and denying them due process. It has created an American gulag in which thousands of detainees, including many innocent of any wrongdoing, have been subjected to ritual abuse and humiliation. It has delivered suspected terrorists into the hands of foreign torturers.

Under the guise of “enhanced interrogation techniques,” it has succeeded, in Mayer’s words, in “making torture the official law of the land in all but name.” Further, it has done all these things as a direct result of policy decisions made at the highest levels of government.

To dismiss these as wild, anti-American ravings will not do. They are facts, which Mayer substantiates in persuasive detail, citing the testimony not of noted liberals like Noam Chomsky or Keith Olbermann but of military officers, intelligence professionals, “hard-line law-and-order stalwarts in the criminal justice system” and impeccably conservative Bush appointees who resisted the conspiracy from within the administration.

Above all, the story Mayer tells is one of fear and its exploitation.

That fear should trump concern for due process and indeed justice qualifies as a recurring phenomenon in American history. In 1919, government-stoked paranoia about radicalism produced the Red Scare. After Pearl Harbor, hysteria mixed with racism led to the confinement of some 110,000 Japanese Americans in internment camps. The onset of the Cold War triggered another panic, anxieties about a new communist threat giving rise to McCarthyism. In this sense, the response evoked by 9/11 looks a bit like d
