Israel's new ambassador to the United Nations Ron Prosor urged Jewish American leaders on Monday to form a clear and operational plan ahead of the United Nations vote in September regarding unilateral recognition of a Palestinian state.

During a closed meeting of the Conference of Presidents of major Jewish American Organizations in New York, Prosor said that talk was not enough at such a crucial time, and that the U.S. Jewish community must prepare a clear operational plan.

In an unconventional appeal for unity, the new ambassador, who started serving as Israel's UN envoy less than a week ago, urged the Jewish leaders to work together despite their differences ahead of the September vote.

Prosor stressed before the Jewish leaders that they must take advantage of the Jewish community's connections with decision makers in order to get results.

Prosor also said that regardless of the outcome of the UN vote, a Palestinian state will not be created and added that the UN is not authorized to dictate borders between countries. He stressed that a unilateral recognition of a Palestinian state will bring about another cycle of violence that will only lead to a dead end.

Least week Prosor said that the September vote was at the center of the Israeli delegation's life.

"The mission regarding the unilateral declaration is one heck of a challenge, but I believe the chances of the declaration to succeed are actually very small. It will only bring things back and take nothing forward; I say that as the director general of the Foreign Ministry during the disengagement from Gaza. Unilateral moves are not constructive," Prosor said after his first day on the job, emphasizing that there was still time to act before the vote.
