terrorism
Acts of violence committed by groups that view themselves as victimized by some notable historical wrong. Although these groups have no formal connection with governments, they usually have the financial and moral backing of sympathetic governments. Typically, they stage unexpected attacks on civilian targets, including embassies and airliners, with the aim of sowing fear and confusion. Israel has been a frequent target of terrorism, but the United States has increasingly become its main target. (See alsoSeptember 11 attacks, Osama bin Laden, Hezbollah, and Basque region.)
