None of the Arab leaders referred to themselves and other Arabs as Palestinians during British rule. When they called for the extermination of Jews, they always called for Jihad in the name of Arabs. Neither any of the Arabs in the West Bank or Gaza came up with any idea of a Palestinian state (and nationality) state before the 1960s.
Gaza was part of Egypt, and Wes Bank was part of Transjordania. None of the Arabs in either region asked Egypt or Jordan to have their own state. Suddenly they wanted one when they lost those lands after starting another war against Israel.
Arafat completely invented Palestine as a state and nationality in the 1960s after ARabs lost another war to eradicate the Jews from the river to the sea. Also, Arafat invented the genocidal slogan "From the River to the sea, Palestine will be free"

This is the list of Jewish settlements attacked by Arabs before 1947 and during British rule.

Metula (1920)
Kfar Malal (1921)
Kfar Saba (1921)
Kfar Uria (1929)
Ruhama (1929)
Motza (1929)
Poria (1929)
Gaza (1929)
Hartuv (1929)
Hulda (1929)
Beit She'an (1936)

Although Arabs feel connected to the land, so do Jews. Jewish kingdoms/states existed 3 times in history. Palestinian state never existed.
Many Arabs refused the call of Arab leaders in 1948 that asked them to abandon Israel so they could freely cleanse it from Jews. Although hundreds of thousands left in panic. Many left. Now there are 2 million Arabs living in Israel. They are the children and grandchildren of these Arabs. They have their own political party in parliament and their own judges in the Supreme Court. They have all rights as Israelis. They even created their own IDF brigades in 1948 (that exist until now) to fight against Arabs they attacked Israel.
Please read about the facts. And I mean information from before the year 2000, like official documents, newspaper articles, books and documentaries. Not made-up lies that have been repeated by Al Jazeera since 2005.
