Sure, but they [the secular org, The Popular Front for the Liberation of Palestine] are adopting a practice that arose in a culture whose religious sensibilities inform thir own secular ones.

I used to believe this.
It appears to have a lot going for it as an explanation, sounding both sensible and neatly self-evident.
Trouble is, it ignores the hidden in plain sight obvious: suicide bombing as a tactic is used in the absence of surface to surface and air to surface missiles, bomber commands and artillery. Note that Hezbollah, an org which is not shy about its religious pedigree, did not employ suicide tactics against the IDF during the most recent Lebanese/Israeli conflict. The Lebanese possessed other, more lethal means. Anti-tank guided missiles, such as the Russian made METIS-M, are a great deal more devastating than deploying a man, wearing a bomb belt, running towards an armored vehicle.
If you review the history of Japanese Shimpu (aka Kamikaze) pilots and other suicide-based initiatives, you'll note that, cultural tropes notwithstanding, Japanese militarists did not settle upon the technique until the war had decisively turned against Japan and her ordinance production suffered major deficits.
But, whenever people talk about the Pacific War suicide attack phenomenon, cultural/religious explanations are given prominence over and above practical considerations.
We tend to do the same thing when discussing ME suicide bombings.
