A brief, analytical assessment of the questions that greater migration pose for individual states with their different traditions, policies, and experiences at a time when porous borders circumscribe their independence. The author, a research fellow at the Royal Institute of International Affairs, takes a moderate view of a situation that has produced anticipatory panic and pervasive resentment. She argues that immigration problems and policies need to be made clear to the citizenry and not, as often happens, disguised. Migration is an old European phenomenon, but it changed in character with the mass movements after 1945 and again with the end of the Cold War. In 1991, Western Europe received 1.5 million foreigners; in 1992, Germany received over 500,000 asylym applications and the United Kingdom 20,000. The political, cultural, and socioeconomic implications of these movements are dealt with succinctly.
