Foreign Minister Javad Zarif reiterated that “it’s immaterial for us who sits in the White House. For us, what is important is how they behave… the U.S. [has] to prove to the rest of the JCPOA participants, particularly to Iran, that it’s going to act responsibly, that it’s not going to make demands outside the scope of the JCPOA, and it’s going to basically stop causing damage to Iran, and compensate us for all the damages”. “We do not renegotiate what we already negotiated”. Zarif added. Referring to Iranian prisoners in the U.S., he declared that “we are prepared to exchange all of them… Let’s not put one person in front of another. Let’s do a universal deal”. He went on to remark with respect to the killing of Qassem Soleimani that “I’m not in the business of making threats, but the book is not closed”. The U.S. Special Representative for Iran, Elliot Abrams, reacted by warning that “should Iran commit acts of terrorism against Americans, you can be sure that they will pay a very heavy price”.
