Ever hear of the 1972 Isreali airport terrorist attack? I just learned of it. The PLO hired Japanese mercenaries... how's that for getting someone else who is utterly innocent looking to the security dept of an airport, to do your dirty work in hope no one finds out who is actually to blame?

The Lod Airport massacre was a terrorist attack that occurred on 30 May 1972, in which three members of the Japanese Red Army recruited by the Palestinian group called the Popular Front for the Liberation of Palestine – External Operations, attacked Lod Airport near Tel Aviv, killing 26 people and injuring 80 others.

Who the hell are the Japanese Red Army, and why haven't you ever heard of them? Well, they failed to accomplish their proclaimed goals, and instead had to get work as mercenaries, apparently, to put food on the table. I mean seriously, who the hell ever heard of the Symbionese Liberation Army either? 

Neither of these "armies" ever fought a war. So, it's not like they were legit. 

An international terrorist group of only 6 people, formed around 1970 after breaking away from Japanese Communist League-Red Army Faction. Whatever that was. 

The JRA's historical goal has been to overthrow the Japanese Government and monarchy and to help foment world revolution. 

Ummm, apparently, as I've never heard of them, they never did anything that even hinted at any intention of overthrowing the Japanese govt. https://unseenjapan.com/red-army-faction/ if you want to read a longwinded account of it

three members of the Japanese Red Army recruited by the Palestinian group called the Popular Front for the Liberation of Palestine – External Operations (PFLP-EO), attacked now Ben Gurion International Airport near Tel Aviv, killing 26 people and injuring 80 others. Two of the attackers were killed, while a third, was captured after being wounded.

The dead comprised 17 Christian pilgrims from Puerto Rico, a Canadian citizen, and eight Israelis, including Professor Aharon Katzir, an internationally renowned protein biophysicist. Katzir was head of the Israeli National Academy of Sciences and a popular scientific radio show host; he was also a candidate in the upcoming Israeli presidency election. His brother, Ephraim Katzir, was elected President of Israel the following year.

Because airport security was focused on the possibility of a Palestinian attack, the use of Japanese attackers took the guards by surprise. 

The attack has often been described as a suicide mission, but it has also been asserted that it was the outcome of an unpublicized larger operation that went awry. The three perpetrators had been trained in Baalbek, Lebanon; the actual planning was handled by the head of PFLP External Operations. 

In the immediate aftermath, Der Spiegel speculated that funding had been provided by some of the $5 million ransom paid by the West German government in exchange for the hostages of hijacked Lufthansa Flight 649 in February 1972
