'Collaborating with the mullahs': Iranian dissidents warn US not to return to the nuclear deal

While Iran announced that it is escalating its nuclear program, despite the Vienna talks aimed at preventing just that, Iranian activists are speaking out to Fox News.

"If the U.S. goes back to the nuclear deal, that's the same thing would happen as happened back in 2015. Iran, the regime of Iran, is going to gain almost $160 billion and 1.7 billion Euros, and yet it is not going to stop its nuclear actions, and actually they even develop their ballistics and drone military drone programs."

"You asked what will happen if the United States returns to JCPOA? I say frankly that this will be a tragedy," says Sima, another activist who says the administration should not even entertain Tehran's demands about the deal, known officially as the Joint Comprehensive Plan of Action, or JCPOA.
