"One of the reasons why this deal is a good one is that it does nothing to prevent the military option," Carter told reporters on board his flight to the Jewish state, the first stop on a Middle East charm offensive to ease concerns among U.S. allies over the landmark accord, according to France 24.

"We are preserving and continually improving such a military option should Iran violate the terms of the agreement," Carter said as he kicked off a trip to Israel, Saudi Arabia and Jordan to renew U.S. security commitments in the region.

As UNIAN reported earlier, six major world powers and Iran reached a nuclear deal in Vienna on July 14. Under the deal, sanctions imposed by the United States, European Union and United Nations would be lifted in return for Iran agreeing long-term curbs on a nuclear program that the West has suspected was aimed at creating a nuclear bomb.
