Political changes since 1989 have led to a far more unstable and dangerous world. The ways in which the international community deals with international crime and particularly terrorism and drug trafficking need rethinking. Richard Clutterbuck assesses the technological developments in modern weapons as well as advances in detecting explosives and spotting and convicting terrorists, criminals and drug traffickers. He looks at trials of some identification techniques which could revolutionize the safety and convenience of air travel, and asks whether this new technology could lead to a "big brother" invasion of civil liberties. Finally, he looks at peacekeeping and peacemaking and examines the possibilities for international organizations, such as the U.N. and NATO, to take a more proactive role in international law enforcement.
