Iranians’ approval of the 2015 nuclear deal is growing, but so is their appetite for restarting the country’s suspended program if the Donald Trump administration stops implementing the accord.

According to a survey released today by the Center for International and Security Studies at Maryland (CISSM) and IranPoll.com, 67.1% of Iranians now approve of the Joint Comprehensive Plan of Action (JCPOA). That compares with 55.4% who said so soon after Trump’s election and 62.6% a year ago.

At the same time, some 55.4% of Iranians would approve of their government restarting aspects of the nuclear program that were limited by the JCPOA if the United States walks away from the deal. That’s up from 48.4% before Trump’s election.

The change in outlook comes amid growing signs that Trump may be getting ready to act on his comments disparaging the nuclear accord. The president has repeatedly challenged the recommendations of his top foreign policy advisers to continue implementing the JCPOA, telling The Wall Street Journal on July 25 that he believed Iran was not complying and suggesting that he might not provide the necessary recertification in October.
