Munich Olympics: Israeli propaganda? This is a little more nuanced that I would have written Arafat’s obit:

In subsequent years, guerrillas from various Palestinian factions hit the headlines with hijackings, bombings and assassinations, most notably the kidnapping and killing of 11 Israeli athletes at the 1972 Munich Olympics.
Arafat refused to discuss such attacks, though he has always denounced terrorism as a tactic. Whether or not he was personally involved remains a matter of conjecture.
