The Assad regime in Syria is corrupt and unstable, depending on Saudi Arabian subsidies, while the Egyptian regime rests on millions of impoverished workers and peasants. Millions of workers live in shanty towns and millions of peasants suffer terrible diseases because they lack even basic amenities of sanitation and fresh water. These regimes can't fight anything-let alone Zionism and imperialism. The Palestine Liberation Organisation depends on Saudi Arabian money and Syria for physical survival. All the bravery of the PLO guerillas can only lead to an impasse.
Arab workers are the key.
The Egyptian working class is at least the size of Russia's working class in 1917. These workers have the power to change the Middle East.
