"Even if Iran does not walk away or promptly returns to the table, its negotiators are likely to adopt more extreme positions in response."

"Our goal is to conclude the major elements of the deal by the end of March and then to complete the technical details by June."

"Today, as the result of the constraints in the JPOA, Iran has halted progress on its nuclear program and it has rolled it back in key areas for the first time in a decade."

"Overall, however, we assess that we still have a credible chance of reaching a deal that is in the best interest of America's security, as well as the security of our allies."
