Iran Nuclear Deal in US Interest

European Union foreign policy chief, Federica Mogherini, said it is in the interest of the US that last year's nuclear agreement between Tehran and world powers continue to be implemented following the election of Donald Trump as US president.

"I think it is in the interest of the United States that the deal [formally known as Joint Comprehensive Plan of Action] continues to be implemented," Mogherini said in an interview with the Wall Street Journal in Brussels on Wednesday.

"The president-elect seems inclined to define his choices … on the basis of American interests," she said.

"The fact that the deal is fully implemented by both sides has delivered on the impossibility for Iran to have a nuclear weapon."

During his presidential campaign, Trump, who defeated his Democratic rival Hillary Clinton in the November 8 election, had promised to annul the deal, which he referred to as a "disaster" and "the worst deal ever negotiated".

Mogherini said it was impossible for Trump to demand fresh concessions from Iran on its nuclear program.

"It is an international agreement in the framework of the United Nations. There is no way the agreement can be reopened bilaterally."

She warned that one of the first fallouts of a US decision to walk away from the Iran deal would be a clash with Russian President Vladimir Putin who helped secure it.

Iran and P5+1 (Russia, China, the US, Britain and France, plus Germany) reached the nuclear deal in July 2015 and implemented it in January this year.

While Tehran has fulfilled all of its commitments under the deal, Washington has failed to fully carry out its undertakings.
