I’m not convinced by University of Chicago professor Robert Pape’s arguments, but his 2005 analysis (here summarised by Business Week’s Stan Crock) of suicide bomber stats remains extremely interesting:
Sri Lanka’s Tamil Tigers, a Marxist-Leninist Hindu group opposed to religion, committed the largest number of suicide attacks, 76. The Kurdish PKK, which used the tactic 14 times, is headed by a secular Marxist-Leninist, Abdulah Ocalan. The Popular Front for the Liberation of Palestine, another Marxist-Leninist group, and the al-Aqsa Brigade, which has ties to the socialist Fatah movement, account for a third of the attacks against Israel. Communist and socialist groups account for 75% of the attacks in Lebanon. Islamic fundamentalists, he concludes, were associated with about only half of the attacks from 1980 to 2003.
Only half! For the rest of the time we should be going after commies.
