You are trying to justify unjustifiable. Jews conquered the land, and they had to get read of the inhabitants on that land. They developed the plan to do that officially and efficiently. They started with ethnic cleansing way before the war broke out.
Plan Dalet (also known as Plan D) was the blueprint used by the new Israeli army and its militia forerunner to expel indigenous Palestinians from their homeland during Israel’s establishment in 1948.
Today, this act of mass expulsion would be called ethnic cleansing.
Officially adopted on March 10, 1948, Plan Dalet specified which Palestinian cities and towns would be targeted and gave instructions for how to drive out their inhabitants and destroy their communities. It called for:
“Destruction of villages (setting fire to, blowing up, and planting mines in the debris), especially those population centers which are difficult to control continuously...
“Mounting search and control operations according to the following guidelines: encirclement of the village and conducting a search inside it. In the event of resistance, the armed force must be destroyed, and the population must be expelled outside the borders of the state.”
