And why is that, pray tell? Israel accepted the borders outlined by the UN. All of the Arab states rejected it. I sometimes wonder if the people actually living there would have accepted it, their fate has been entirely determined by the Arab states, who not only rejected the initial borders, but have continued to wage war on Israel and sponsor acts of terror on it. And so your claim that all except Israel have borders is dumb! There is no Palestinian state, or Arab state by any other name, in the region, therefore, it does not have defined borders.
