Israeli diplomats have put foreign leaders on notice that their country will consider its historic peace accords with the Palestinians null and void if they ask the United Nations for a state, the Associated Press reported Wednesday, November 14. An Israeli Foreign Ministry document also instructs diplomats to tell world leaders that Israel will retaliate against the move, without specifying details. The Palestinians say they will ask the U.N. General Assembly on Nov. 29 to give them upgraded observer status. A draft resolution floated by the Palestinians seeks international recognition of their state in the West Bank, east Jerusalem and the Gaza Strip, territories captured by Israel in the 1967 Mideast war. Israel and the U.S. strongly oppose the effort, saying all matters must be resolved through negotiations. Late Tuesday, U.N. chief Ban Ki-moon warned that the planned Palestinian move would undermine negotiations.
