The bombings of the World Trade Center and the Oklahoma City federal building have shown that terrorist attacks can happen anywhere in the United States. Around the globe, massacres, hijackings, and bombings of airliners are frequent reminders of the threat of terrorism. The use of poison gas in the Tokyo subway has raised the specter of even more horrible forms of terror — including the use of nuclear, chemical, and biological weapons.In this book, Philip Heymann argues that the United States and other democracies can fight terrorism while preserving liberty and maintaining a healthy, unified society. Drawing on his experience in the US Departments of State and Justice, he shows how domestic and foreign intelligence-gathering can thwart terrorism, how the United States must cooperate and share information with its allies, and how terrorism can be prevented in many cases. Terrorism will never disappear completely, but the policies Heymann offers can limit the harm to Americans and protect the integrity of US governmental processes.
