The U.S. envoy to the IAEA, Jackie Wolcott, asserted that "Iran will find that nuclear escalation of the kind it now threatens will only lead to further isolation and pressure. The path forward is clear: Iran must return to the negotiating table and cease its destabilising actions". "Iran has claimed that it continues to comply with the JCPOA, but it is now reported to be in clear violation of the deal", Wolcott added. "This should be of great concern to all of us. The U.S. calls on Iran to return to compliance without delay".
