Abbas, 84, has made similar threats before and not implemented them.
Greenblatt also said that the conflict could not be solved on the basis of global consensus or with references to inconclusive worldwide law and United Nations resolutions. He suggested that Security Council resolutions on those issues are unenforceable. He said a decision on the release of the political component of the U.S. plan would be made "soon".
Several council members emphasized the importance of United Nations resolutions during Tuesday s meeting.
Such statements have to be agreed by consensus and on Wednesday the U.S. told its council counterparts it could not support the text, diplomats said. All settlements on occupied Palestinian lands are illegal under worldwide law.
The U.S.' Middle East proposal has two major components - a political piece that addresses core issues such as the status of Jerusalem, and an economic portion that aims to strengthen the Palestinian economy.
Addressing a regularly scheduled UNSC on "the situation in the Middle East", Greenblatt said that "international consensus is not worldwide law". "Even if I had a great peace plan, if we don't figure out how to make sure that Iran doesn't spoil it, how much success are we really going to have?"
Speaking to Jewish News, he said: "These demolitions aren't just the latest in a long and unacceptable series of demolitions they set a risky precedent and inflict further harm on the prospects for peace and a two state solution".
He said it would provide enough detail for people to see "what compromises will be necessary to achieve a realistic, lasting, comprehensive solution to this conflict".
The Popular Front for the Liberation of Palestine (PFLP) said in response that suspending the agreements with Israel is a step in the right direction, which must be followed with a full withdrawal from the Oslo agreement and all its obligations.
However American envoys told the Security Council that they would veto any draft United Nations statement criticising the demolitions. He also urged the Security Council to encourage the parties back to the negotiating table. A revised three paragraph draft statement was circulated, but the United States again said it did not agree with the text, diplomats said.
