The terms "terrorism" and "terrorist" gained renewed currency in the 1970s as a result of the Israeli–Palestinian conflict, the Northern Ireland conflict, the Basque conflict, and the operations of groups such as the Red Army Faction. Leila Khaled was described as a terrorist in a 1970 issue of "Life" magazine. A number of books on terrorism were published in the 1970s. The topic came further to the fore after the 1983 Beirut barracks bombings and again after the 2001 September 11 attacks and the 2002 Bali bombings.
