Suicide bomber is PC euphamism. The purpose of his actions is murder, not suicide. The news should say "15 innocent civilians were murdered today. State sponsored murderers from the Palistiniam Authority murdered 15 innocent people when ..." Murder of civilians is the goal, intention, and result. Thus even the term "militant" is misapplied - these cowards go after little girls and people on buses - they never attack a military installation.
Homicide bomber is euphemistic in its own way - murder would be more accurate - as in "First degree murder" which is what these are.
