"It is impossible to revise the Iran Nuclear Deal… improve, supplement, correct it in the current situation. Too much has happened recently, aggravating the mistrust between Washington and Tehran," Ryabkov said in an interview.
The Russian diplomat reminded that exists a range of issues, unrelated to the contents of the JCPOA, which the United States was adding to the international agenda.
"Iran is accused of all kinds of offenses and criticized for actions, which, in our view, reflect the attempts of the country to secure its own interests. Instead of having a normal dialogue, the US applies blackmail methods," Ryabkov underlined.
Commenting on the US Nuclear Posture Review, Iranian Foreign Minister Javad Zarif said that the doctrine showed US increasing reliance on nuclear weapons, stressing that such an approach would bring humanity closer to annihilation. He added, that he "obduracy" of US President Donald Trump in "killing" the agreement.
On January 30, Donald Trump asked the Congress to address the flaws in the "terrible Iran nuclear deal." Earlier that month, Trump announced that he would waive sanctions on Iran as required by the JCPOA, but said this would be the last time.
In July 2015, Iran and the P5+1 group of nations — the United States, Russia, China, France and the United Kingdom plus Germany — signed the JCPOA. The agreement stipulates a gradual lifting of sanctions imposed on Iran in exchange for Tehran maintaining the peaceful nature of its nuclear program.
