Mahmoud Abbas holds many titles. He is the head of the Fateh movement, chairman of the PLO’s executive committee and president of the state of Palestine.
Technically and legally, the Palestine Liberation Organisation is superior. The state of Palestine, declared a non-member state in the UN in 2003, is subservient to the PLO.
In mere numbers, the state of Palestine, under occupation and lacking sovereignty except in large West Bank cities, is not as important as the PLO, which represents some 12 million Palestinians inside and outside Palestine.
But the PLO is an empty shell. It was originally made up of guerrilla movements that have since been silenced, and its offices around the world have been replaced by embassies of the state of Palestine.
