What happened in Palestine after the creation of Israel Was there an ethnic cleansing ?

Yes, there was ethnic cleansing committed towards the Palestinian natives. In Arabic, it is called the Nakba which means “catastrophe” or “calamity”, and it specifically refers to the ethnic cleansing of Palestine at the hand of Zionist militias between 1947-1948 and the subsequent establishment of the state of Israel. This campaign of ethnic cleansing took place before, during and after the war of 1948, and saw approximately 800,000 Palestinians expelled from their homes, and over 530 Palestinian communities demolished. Today, Israel can only maintain itself as an ethnocracy by perpetuating the displacement of these refugees and their descendants.
