How did Israel form ?
Israel unilaterally declared its independence (from what, beats me) on Palestinian lands, ethnically cleansed at least 300 thousand Palestinian, and conducted massacres against indigenous Palestinian natives BEFORE any Arab rescue army entered Palestine. Between 750,000 and one million (80% of the native Palestinian populace at that time) was the number of Palestinians expelled and made refugees by Zionist paramilitaries, and subsequently Israeli forces, during Israel’s creation in 1947-49.
The depopulation of 560 Palestinian towns and villages in 1948 by Zionist militia and Israeli army could not have happened without an organized campaign of massacres and atrocities, of which 156 were recorded in Table 3.2 Atlas of Palestine 1917- 1966.
The Zionist invasion which started in April 1948 led to the depopulation of 220 towns and villages in 6 weeks till 14 May 1948, BEFORE the state of Israel was declared while Palestine was supposedly under the British Mandate protection BEFORE any regular Arab force could intervene.
Israel was established through warfare and the creation of facts on the ground. Facts it created through the massacre of Palestinians and the ethnic cleansing of hundreds of villages. This is how the modern state of Israel came into the world, and no amount of sophistry or euphemization can lend that any legitimacy.
