How does the term kamikaze relate to modern day terrorism?

The Kamikaze airplanes were not fully functional fighter airplanes. They carried no weaponry, and were completely stuffed with explosives. So their pilots were no more than (flying) suicide bombers. Like modern terrorist their aim was only to strike terror in enemies' hearts, both parties then and now knew that their attacks had a mostly psychological effect and would themselves not win any war. Another similarity is that not all of the suicide bombers and kamikaze pilots were (and are) willing victims. Many were and are put under great pressure to make 'the ultimate sacrifice'. Both finally felt subject to a higher power under whose orders they acted: the Japanese pilots under the (then Godly) Japanese Emperor, the mostly Muslim terrorist are convinced that this is what Allah wants.
