...contrary to conventional explanations, suicide attacks follow a certain strategic logic. From 1980 to 2006, Pape has counted 870 completed suicide attacks -- with the Iraqi insurgency accounting for the majority of such attacks in recent years.

Of the total, Pape has found that 824 of the attacks, or 95 percent, have come from groups that are fighting against military occupations of their homeland. Pape found that 85 percent of all the suicide attacks in the last quarter-century have come about in response to U.S. combat operations. There were eight times as many suicide attacks in Iraq in 2006 as there were in 2003.

Pape believes his findings offer empirical proof that the wars in Iraq and Afghanistan have not lowered the risk of suicide attacks. Contrary to President Bush's argument that those wars provided the best way to lower the risk of suicide terrorism, Pape says the data show that launching overseas wars appears to be a way to increase the risk of suicide attacks. Improved homeland security, rather than foreign military occupations, the political scientist argues, is the way to lower the risk of suicide terrorism.

Unlike many of the other theories circulating in Washington, his theory can be put to a simple test, Pape said. For the first time, Pape said in an interview at the political science convention in Chicago, the troop buildup in Iraq has aggressively targeted Shiite groups, such as Moqtada al-Sadr's Mahdi Army. Until now, suicide attackers have been largely limited to Iraq's minority Sunni population. Pape believes that U.S. operations against Shiite groups will cause increasing numbers of Shiites to see the Americans the way many Iraqi Sunnis do -- as occupiers, rather than liberators.
