But immediately after they lost the partition vote, it was like the pent-up hatred all exploded at once.
The first victims were on a bus to Jerusalem. Some were killed instantly from a grenade hurled into the bus; one of the injured passengers was murdered as he tried to tend to his injured wife. Another victim was on her way to Jerusalem to get married.
The reasons for the hate have not changed a bit from then to today. They were not murdered because of "occupation" or "refugees" or any of the dozens of other justifications that have been since used to minimize the horror of these unabashed terror attacks.
Their "crimes" were simply because they were Jews with the desire to live in their own nation, at peace with their neighbors. What the world recognized instinctively in 1947 - that Jews deserve the right to self-determination - was to be tested by a massive temper tantrum of Arab supremacists who were willing to attempt a second genocide against the Jews rather than face what they consider "humiliation."
And, yes, the proper word for someone who considers another people's lives less important than Arab honor is an Arab supremacist.
