Answering your questions: Because this whole conflict started by the Arabs refusal to accept the partition plan of the UN, Settlements freezed for 10 months and this only once in the history of Israel and guess who did it - the present Netanyahu Government. What reaction he get from Mr. Abbas: 9 months of waiting for negotiations, then he came to the table to ask that the settlement freeze be prolonged. If there is to be a Palestinian state side by side with Israel (of which I too am a supporter) then it is obvious even to kindergarten children that there cannot be a right of physical return. It is utterly illogical that Palestinians want a state in order to send their people to Israel - for what the state then. Please be realistic.
