US is loser by abandoning Iran nuclear deal: Rouhani

Iran's president boasted Sunday that the United States has lost against the Islamic republic's "righteousness and wisdom" by walking out of the landmark nuclear deal.

"Everyone knows that America has lost legally and politically by giving up on its international obligations and that we have achieved victory," said President Hassan Rouhani in a speech at the University of Tehran to mark the beginning of the school year.

"There are but a few countries in the world that would call the US withdrawal from the JCPOA (nuclear deal) a good move," he added.

"Those that are cautious express disappointment, those that are more frank say it was a mistake, and the outspoken say it was illegal."
