That reflected a fall-off in support from when the agreement was signed in July 2015 by the five members of the UN Security Council (China, France, Russia, the United Kingdom and the United States) plus Germany and the European Union. Several polls showed a barely informed public was supportive (when offered details of agreement, support went up 9 to 10 points) (see below).

In general, as the debate proceeded in 2015, partisanship, pro and anti-Obama sentiment, and criticism of the agreement took a toll on its support. The bottom line is that Iran is not a popular country in the U.S.; its general behavior in the Middle East is controversial; and the agreement, for its benefits, still is a negotiated document with many unpopular compromises.
The future of the agreement, which is still supported by the other signatories, is in the hands of the Trump administration, Congress and the foreign policy establishment.
