From the IRA to the Islamic State: The Evolving Terrorism Threat in Europe
Europe faces a significant threat from terrorism, particularly from Islamic extremists and far-right groups. Europe’s increasingly aggressive approach to terrorists — including prosecuting individuals for planning to travel abroad to join terrorist groups, censoring extremist Internet material, punishing Internet companies that fail to remove extremist material, and improving intelligence cooperation — have largely gone unnoticed in the United States.
This report, published by the Center for Strategic and International Studies (CSIS), takes a renewed look at Europe and compiles new data on the threat to Europe. It also examines the counterterrorism response by European governments, especially the United Kingdom and France.
