John Kerry actually said...

"What this agreement is supposed to do is stop them from having a nuclear weapon."

"If the P5+1 agreement is rejected by the United States, I don't think we can rely on those other countries keeping that money locked up."

"It is a lot easier to push back against an Iran that doesn't have a nuclear weapon rather than one that does."

"Under the agreement, Iran's leaders are permanently barred from pursuing a nuclear weapon, and there are permanent restraints and access provisions and inspection provisions to guarantee that."
