When Yasser Arafat, then a young engineer in Kuwait, founded the "Palestinian Liberation Movement" (whose initials in reverse spell Fatah), he meant first of all liberation from the various Arab leaders, so as to enable the Palestinian people to speak and act for itself. That was the first revolution of the man who made at least three great revolutions during his life.
It was a dangerous one. Fatah had no independent base. It had to function in the Arab countries, often under merciless persecutions. One day, for example, the whole leadership of the movement, Arafat included, was thrown into prison by the Syrian dictator of the day, after disobeying his orders. Only Umm Nidal, the wife of Abu Nidal, remained free and so she assumed the command of the fighters.
