Suicide bombings in Iraq are among today's most pressing and puzzling issues. The number of attacks is extraordinarily high: Although hard to pinpoint, the total is certainly greater than all such incidents in other conflicts, including Israel-Palestine and Sri Lanka, combined. The attacks, most of which are by car bombs, are primarily directed by violent Islamists against fellow Muslims, and civilians are the targets of choice. The bombers are mostly foreign, not Iraqi, although we still do not know who is behind most attacks (the identity of 58% of the perpetrators is unknown). Clearly suicide bombing in Iraq is largely an imported phenomenon.
