JERUSALEM — Israel’s Foreign Ministry has warned foreign governments that a successful Palestinian bid for enhanced status at the United Nations this month could lead Israel to cancel the Oslo peace accords and, possibly, to oust President Mahmoud Abbas and dismantle his Palestinian Authority, according to official documents made available to reporters on Wednesday.

The threats reflect the last-minute brinkmanship under way as the Palestinians forge ahead with plans for a vote on Nov. 29 in the United Nations General Assembly, having rejected a personal plea to hold off from President Obama as they and the Israelis focus their final lobbying efforts on a divided Europe.

Last week, the Palestinians distributed a draft resolution to the 193 member states in the first practical step of the campaign for international recognition of a future state in the West Bank, Gaza and East Jerusalem. They also seek to upgrade their status to that of a nonmember observer state in the United Nations system.

There is little doubt that a vote will pass; the Palestinians are expected to win a majority of the member votes in the General Assembly. But both they and the Israelis are placing great importance on gaining the support of what they call a “moral majority” of important Western nations.
