"There will be no sunset to the deal that we are working to finalize. No sunset - none. The parameters of this agreement will be implemented in phases. Some provisions will be in place for 10 years, others will be in place for 15 years, and others still will be in place for 25 years. But certain provisions, including many transparency measures, will be in place indefinitely into the future. They will never expire, and the bottom line is that under this arrangement, the international community will have confidence that Iran’s nuclear programme is exclusively peaceful. Providing, of course, that the provisions are adhered to. And if they aren't, we of course have provisions that empower us to deal with that."
