The US envoy to the United Nations says if diplomacy fails and the nuclear deal cannot be restored with Iran, the international community will increase pressure on the Islamic Republic. 

At a press conference Ambassador Linda Thomas-Greenfield said on Tuesday that “there’s still a lot more work to be done [on the JCOPA], we don’t have an agreement just yet, and it’s possible we might not get there”. The US is set to take the rotational presidency of the Security Council later this month.

She noted that “if diplomacy does not succeed, then we’ll continue to work very closely with others in the international community to increase the pressure on Iran”.

Thomas-Greenfield stated that some substantial progress has been made in resolving a significant number of the issues necessary for the US to come back into the deal on a compliance-for-compliance basis, and “we’re continuing to work on that effort, and we’ll see where it leads”.

She said president Joe Biden made a solemn commitment that Iran must not be allowed to acquire a nuclear weapon, but he also made a commitment that he was prepared to go back into the deal, or the Joint Comprehensive Plan of Action. 

Iran’s foreign minister said earlier on Tuesday that Washington “must correct Trump's illegal behavior with a realistic approach” and take a political step to reach a nuclear agreement, insisting that Tehran and Washington are still exchanging messages through the European Union despite the halt in Vienna talks.
