Israel now believes the chances of a new nuclear deal being signed by Iran and the West are “slim to none,” according to Israeli diplomatic officials.

“The possibility that the sides will sign a deal in the foreseeable future is shrinking exponentially,” the officials told Israeli daily Israel Hayom.

Until a month ago, the prevailing assessment in Israel diplomatic and security circles was that the United States and Iran would indeed reach an agreement. This belief was based on the U.S. administration’s enthusiasm for a return to the 2015 Joint Comprehensive Plan of Action (JCPOA) nuclear deal with Tehran, to which many current administration members were signatories.

During the negotiations in Vienna surrounding a return to the 2015 agreement, which the United States unilaterally exited in 2018 under President Donald Trump, Washington has made numerous concessions to Iran, prompting two senior members of the U.S. negotiating team to resign.

A draft version of a new agreement had already been submitted, and it appeared likely that a signing date would be announced soon after the parties last left Vienna. However, instead of announcing either acceptance or rejection of the draft agreement, Iran set out a number of new conditions, including a demand that the United States remove the Islamic Revolutionary Guards Corps from its list of foreign terrorist entities.
