Suicide bombers

A suicide attack is any violent attack in which the attacker(s) has the expectation of death, combined with the simultaneous expectation of the death or destruction of the specified target. Suicide attacks have occurred throughout history, often as part of a military campaign such as the Japanese Kamikaze pilots of World War II, and more recently as part of terrorist campaigns, such as the September 11 attacks.

While there were few, if any, successful suicide attacks anywhere in the world from the end of World War II until 1980, between 1981 and September 2015, a total of 4,814 suicide attacks occurred in over 40 countries, killing over 45,000 people. During this time the global rate of such attacks grew from an average of three a year in the 1980s, to about one a month in the 1990s, to almost one a week from 2001 to 2003, to approximately one a day from 2003 to 2015. Suicide attacks tend to be more deadly and destructive than other terror attacks because they give their perpetrators the ability to conceal weapons, make last-minute adjustments, and because they dispense with the need for remote or delayed detonation, escape plans or rescue teams. They constituted only 4% of all terrorist attacks around the world over one period (between 1981 and 2006), but caused 32% of all terrorism-related deaths (14,599). Ninety per cent of those attacks occurred in Afghanistan, Iraq, Israel, the Palestinian territories, Pakistan, and Sri Lanka. Overall, as of mid-2015 about three-quarters of all suicide attacks occurred in just three countries: Afghanistan, Pakistan, and Iraq.

Suicide attacks have been described as a weapon of psychological warfare to instill fear in the target population, a strategy to eliminate or at least drastically diminish areas where the public feels safe, and the "fabric of trust that holds societies together".

The motivation of suicide attackers varies. Kamikaze acted under military orders and were motivated by obedience and nationalism. Before 2003, most attacks targeted forces occupying the attackers' homeland, according to analyst Robert Pape. Anthropologist Scott Atran states that since 2004 the overwhelming majority of bombers have been motivated by the ideology of Islamist martyrdom.
