"It's been one year since Trump has been trying to kill JCPOA and hasn't been successful," Rouhani said Sunday, using the technical name of the deal. “This means a victory for international commitments and law against dictatorship… and a long-lasting victory for Iran.”
Rouhani further noted that Americans failed “to trample upon on the world’s public opinion with dictatorship and arrogance, and this is a blow to the US and a success for Iran.”
He said the White House had been standing against the Security Council Resolution 2231, which endorsed the nuclear agreement.
"I am very happy to see that the White House has failed to disrupt international obligations, break loyalty and stand against the resolution of the United Nations Security Council which was the outcome of an agreement among seven countries," he said.
“We proved that a tight knot could be undone at the negotiating table... that Iran is speaking the truth while the enemies are telling lies, and that we are not seeking to develop nuclear weapons,” he added.
The US president on Friday extended waivers of key economic sanctions on Iran, which were lifted under the JCPOA, for another 120 days but said he was doing so “for the last time.”
Trump called on European allies and Congress to work with him to “fix the disastrous flaws” in the nuclear agreement or face a US exit.
Iran says the nuclear deal is not renegotiable and it will stick to the accord as long as the other signatories respect it but will "shred" the deal if Washington pulls out.
Under the deal, Iran agreed to curb its nuclear program, in exchange for lifting of most sanctions.
