The arabs in the area refused to abide by the "two state solution" after the war.
The arabs were the ones that were going to drive the jews into the Mediterranean Sea. It became a civil war, and the jews won.
Then in 1948
Why did Jews in Israel establish a Population Transfer Committee in 1937?
"On the heel of the Peel Committee recommendations, the Jewish Agency created the Population Transfer Committee with an impressive list of executive members, one of whom was Dr Kurt Mendelson from Holland considered to be ‘the expert on the question of population transfer’. He would divide the Palestinian Arabs into 3 categories to be cleared in the first stage of the Transfer Plan:
1. Tenant farmers.
2. Landless villagers working as agricultural labourers.
3. Farmers who owned less than 3 dunums per capita.
"To resettle these people, the Transfer Committee calculated that 1.15 million dunums would have to be purchased in Transjordan and that it would take nearly 10 years to complete the transfer.
"Ben-Gurion opted instead for a total evacuation of Arabs from the proposed Jewish state. He said that he looked at the Jewish part only as a provisional solution '
on the basis that after we build a strong force following the establishment of the state, we will abolish the partition of the country and we will expand to the whole Land of Israel'"
Why do you believe Jews from Europe were/are entitled to Arab land in Palestine?
