Palestine has no history lol, 200 years ago did they have a currency? Did they have a king or a leader? Did they have any poet or a writer that identified as Palestinian? There was no nationality called Palestinian. Arabs were Jordanian, Egyptian, Syrian, but not Palestinan.
Even West Bank was liberated from Jordan and Gaza from Egypt in 1967, not Palestine.
Terrorist activities started by the Arabs, Palestinians were not a nationality back then, search "Massacres in mandatory Palestine" and you'll see who started massacres. British had it coming, they blocked Jews from running away from Europe during the Holocaust and followed the laws of the white book, laws that oppressed Jews.
