"We have put a number of options for ourselves, and those options are ready," Zarif told "Face the Nation" moderator Margaret Brennan, "including options that would involve resuming at a much greater speed our nuclear activities."
Asked how Iran would respond if the president walked away from the deal, Zarif said the country was prepared.
"Those options are ready to be implemented and we will make the necessary decision when we see fit," said Zarif.
"Obviously the rest of the world cannot ask us to unilaterally and one-sidedly implement a deal that has already been broken," he added later.
