WASHINGTON (Dispatches) -- U.S. Secretary of State Antony Blinken on Sunday said the United States has not seen yet whether Iran will do what Washington wants in order to have sanctions removed. “Iran, I think, knows what it needs to do to come back into compliance on the nuclear side, and what we haven’t yet seen is whether Iran is ready and willing to make a decision to do what it has to do. That’s the test and we don’t yet have an answer,” Blinken told ABC News’ “This Week With George Stephanopoulos” program. With a fifth round of discussions ahead, Blinken said, “the first thing that we need to do is put the nuclear problem back in the box.” The talks, he added, helped clarify what both sides needed to do to move forward.
