Is this how israel became "independent"?

Simply before 1945; 90% of the people living in Palestine; now called Israel were Palestinian Arabs and have been living their for hundreds of years; going back to the Roman times; they use to call it Philistine; then comes Rothschild's wealth and WZO (world Zionist organization) in 1898 under the Leadership of Theordel Herzl declared that the Jewish people will have a home in Palestine, And in 1922 The Jewish agency of Palestine was created; however no Jew wanted to leave beautiful Europe and go to fight with Arabs in the desert, it was Hitler atrocities that forced 3 million Jews to go to Palestine from 1944-1952, and when the time was right they over threw 300,000 Palestinians from their homes and declared Palestine ; Israel, and until this day they treat Palestinians like slaves; and we can safely state that Gaza is the first Zionist concentration camp.
