Kerry: World powers won't reinstate sanctions regime

Kerry stresses that the UN Security Council members voted unanimously in favor of the nuclear deal with Iran, and lists various experts from different fields who back the agreement. He adds that the US would suffer greatly in the international arena if the deal were not implemented.

The sanctions on Iran did convince the country’s diplomats to approach the negotiation table, Kerry says, but only after talks began did Iran begin to significantly curb its nuclear program.

If the deal falls, Iran will be closer to a bomb, Kerry adds. Most countries will not reinstate sanctions if the deal is struck down, he says.
