Such comparisons with process of intentions are dangerous and not perceptive. Lieberman may become a burden for Israel, but he was elected as Le Pen in France and U. Bossi in Italy. I do not think that he will be prime minister, I do not think also that Israel would violate any law: Israel does not have such freedom, it is under scrutiny like no other country. Anyway you can think that he should not be part of the government but he has been elected. Hamas was also elected, I did not see your complaints although they committed crimes. If Arabs would stop terror, he may not have been elected. This is the key to peace: Arabs should stop terror.
