Palestinian identity is just so much nonsense. The official definition of that identity encompasses only those parts of the Palestine Mandate which Israel holds today.
The people who live on the parts of the Palestine Mandate that were turned into the Kingdom of Jordan in 1921 are not Palestinians. There is no call to incorporate them into a Palestinian state. The people who lived in the parts of Israel that were captured by Jordan and Egypt in 1948 weren’t Palestinians, and there was no call to turn the land that today comprises the so-called “Occupied Territories” into a state. But in 1967 when Israel liberated those areas– only then did they magically turn into Palestinians.
How is anyone supposed to take this nonsense seriously?
