"There is no inherent right to enrich," Kerry said on ABC's "This Week." "And everywhere in this particular agreement it states that they could only do that by mutual agreement, and nothing is agreed on until everything is agreed on."
Kerry added: "We do not recognize a right to enrich."
Appearing on CBS’s “Face the Nation,” Kerry also disputed Iran’s argument that this deal takes potential military force by the United States off the table.
“No, that’s just not accurate," he said.
In a trio of Sunday interviews -- Kerry also appeared on CNN's "State of the Union," Kerry took on critics of the deal, accusing them of being unwilling to accept a good deal because it's not perfect. Those critics include Israeli leaders and a number of members of Congress.
"You can't always start where you want to wind up," Kerry said on ABC.
