The United States government-backed by the overwhelming support of the American public-takes a hard line against international terrorism. The tenets of official U.S. counterterrorist policy are: make no concessions or deals with terrorists; bring them to justice for their crimes; isolate and apply pressure on states that sponsor terrorism; and bolster the counterterrorist capabilities of countries willing to work with the United States.

In the first four chapters, Paul R. Pillar identifies the necessary elements of counterterrorist policy, he examines why the United States is a prime terrorist target, and he reveals why the counterterrorist policies that seem strongest are not always the most effective.

Chapter 6 focuses on states that sponsor terrorism (including Iran, Libya, North Korea, and Cuba), along with those that enable it to occur (particularly Greece and Pakistan). Pillar examines ways in which the American public's perspective toward terrorism can actually constrain counterterrorist policy, and he concludes that terrorism cannot be "defeated" only reduced, attenuated, and to some degree, controlled. The final chapter summarizes his recommendations f
