The indirect talks between Iran and several other countries to revive the Joint Comprehensive Plan of Action (JCPOA), Iran’s nuclear deal, have begun in Vienna after a five-month hiatus. However, the negotiators involved in the talks have little optimism.

Iran has made what is being correctly termed as “maximalist demands” and has denied access to key nuclear sites to the United Nations watchdog.

While much has changed since the last meeting, several things remain the same: Tehran is digging in its heels and demanding all sanctions by the United States be removed; the U.S. is threatening to walk away from the talks; and the Israelis are threatening to use military force to take out the Iranian nuclear facilities

Iranian Foreign Minister Hossein Amir-Abdollahian said on Monday that there is “no way” to return to the 2015 JCPOA unless all American economic sanctions are lifted.
