WASHINGTON (Reuters) -Washington may need to rethink its approach to Iran if the serious differences between the two countries on resuming compliance with the 2015 nuclear deal cannot be resolved "in the foreseeable future", a senior U.S. official said on Thursday.
"We still have serious differences ... over the host of issues, whether it's the nuclear steps that Iran needs to take to come back into compliance, the sanctions relief that the U.S. would be offering or the sequence of steps that both sides would be taking," the official told reporters on a conference call.
