The war was already in place with Arab irregulars attacking Jews wherever they could all over Palestine,they had already killed over a thousand Jews before the Arab armies moved with their stated intentions. That they did not achieve their stated final objective does NOT mean they did not want to invade all areas containing Jews. It is totally illogical to claim because they could not achieve their stated objectives they did not invade. Aplogia at its finest.
