Prime Minister Binyamin Netanyahu has explained repeatedly over the years that Israel has no Palestinian partner to negotiate with. So news reports this week that Netanyahu agreed that the 1949 armistice lines, (commonly misrepresented as the 1967 borders), will be mentioned in terms of reference for future negotiations with the Palestinian Authority seemed to come out of nowhere.
Israel has no one to negotiate with because the Palestinians reject Israel's right to exist. This much was made clear yet again last month when senior PA "negotiator" Nabil Sha'ath said in an interview with Arabic News Broadcast, "The story of 'two states for two peoples' means that there will be a Jewish people over there and a Palestinian people here. We will never accept this."
