Its the next step in the nuclear deal with the west which was almost scuttled this week with the capture of ten u. S. Sailors in the persian gulf. David martin has that. Reporter the speedy released of the sailor is being portrayed by the administration as years of diplomacy with iran.

Reporter both sides agreed the two boats accidently strayed into iranian territorial waters. Exactly how remains unclear. After being held for 16 hours in the persian gulf, the crew was allowed to get back in their boats and sail out to this american warship. The release came after a series of phone calls between secretary kerry and irans foreign minister, who had developed a working relationship during the long, drawnout negotiations in which iran agreed to suspend its Nuclear Program in return for relief from economic sanctions. The Iranian Foreign minister tweeted he was happy to see dialogue and respect, not threats and impetuousness, swiftly resolve the sailors episode.

Reporter irans desire not to derail the nuclear deal between the two countries may really be what resolved this. Under that deal, the u. S.
