On Jan. 12, Donald Trump is scheduled to decide whether to sign the first of a series of sanctions waivers as part of the Joint Comprehensive Plan of Action (JCPOA). Now more than ever, Iran considers it likely that the United States may leave the nuclear deal, thus imposing new conditions on both Iran and the rest of the world.

Speaking at the annual Tehran Security Conference on Jan. 8, senior Iranian nuclear negotiator Abbas Araghchi spoke about the consequences of a US exit from the accord, saying, “During the past year, Trump has tried very hard to destroy the Iran deal and might do so in the near future. The international community should be ready to deal with the consequences of such action.” Araghchi added that Iran is ready for every future scenario, whether or not the JCPOA is saved.

Meanwhile, during his weekly news conference on the same day, Foreign Ministry spokesman Bahram Ghasemi displayed great caution in answering questions regarding Iran’s possible reaction to the US’ possible refusal to renew the sanction waivers. “We don’t want to judge [things] beforehand. Under the JCPOA, the president of the United States is required to renew the waivers for US sanctions against Iran. If he refuses to do so, we are prepared for any scenario. If the United States decides to withdraw from the JCPOA, Iran’s reaction will make the US government regret its decision.”

Also on Jan. 8, another Iranian official, this time atomic chief Ali Akbar Salehi, issued a warning. Speaking with International Atomic Energy Agency Director General Yukiya Amano, Salehi warned about the consequences of a US breach of its obligations. The next day, Ali Akbar Velayati, a senior aide to Iranian Supreme Leader Ayatollah Ali Khamenei, also reacted similarly, although cautiously, regarding the possibility that Trump would refuse to issue the waivers. While noting that Iran has all options on the table, Velayati also expressed criticism of European countries: “Some of the allies of the United States insist on upholding the JCPOA, yet the United States acts differently. Basically, one side is benefiting from the JCPOA, but it is only Iran that is upholding the promises it had made. This is not acceptable.”
