It looks like there is a plan being discussed whereby the Palestinians would bypass the UN Security Council, and instead go directly to the General Assembly. The idea is that the US would not be "forced" to veto the resolution in the Security Council and the Palestinians would receive upgraded status at the UN along with a big chunk of the EU members voting in favor. The EU is trying to get the US to abstain in the General Assembly. The Haaretz report is here.
According to the same article, "in recent weeks the Foreign Ministry, Military Intelligence, the Shin
Bet security service and the Mossad have distributed a number of
documents stating that a return to negotiations would tone down tensions
and anger against Israel."
