Starting in the 1970s and 1980s, however, a rise of violent activity in Europe by international terrorist groups (such as the Palestine Liberation Organization and Hezbollah) began to prove these traditional European responses to terror inadequate. Governments reacted with more robust and effective-cooperative measures. Still, unlike the enemies the United States faces today, few terrorists in those days sought to debilitate European governments or recruit large numbers of members. And even those that did harbor global religious and ideological objectives (such as the Algerian Islamist Group, or GIA) still tended to employ "old" terrorist techniques.
