Japanese Commies: Suicide attacks are a good thing, actually. (points to the kamikazes)
Yasser Arafat and the PLO: Well, suicide is forbidden by Islam...
Japanese Commies: Then let us demonstrate how a lack of care for one's life makes your terror more effective. (proceeds to shoot up an airport)
Would be an odd twist of history, if suicide attacks and suicide bombings becoming standard practice amongst Muslims can be traced to Japanese Reds deciding to teach Palestinian terrorists about the "kamikaze" pilots.
History ping.
Side note: The JRA may be how the IRA got ahold of Japanese made AR-180s in the early 1970s.
