Trump should stop fantasizing about killing the Iran nuclear deal

To understand President Trump’s recent decision to keep the Iranian nuclear deal alive by waiving sanctions against Iran for the third time—but saying this will be the last time he will do so, unless the deal is significantly renegotiated—requires an understanding of the history of arms control deals negotiated by the United States. Taken in context, the president’s repeated attempts to force a renegotiation of the Iran agreement can be seen as the counterproductive fantasies they have been. They should stop, as the president and Congress turn to focus on more pressing security challenges.
