JNS.org – A strong majority of Americans believe that Iran is not likely to uphold the rules of the framework nuclear agreement announced on April 2, a new survey found.

According to an NBC News poll, conducted in conjunction with SurveyMonkey, among 2,052 adults surveyed from April 6-8, 68 percent believe that Iran is either not too likely or not at all likely to abide by the nuclear agreement, compared with 25 percent who said Iran would honor it.

Additionally, the survey found that 53 percent of Americans believe the Iranian nuclear program represents a major threat to the U.S., compared with only 37 percent who consider it a minor threat and 8 percent who said it was no threat at all.

Despite the skepticism of the framework agreement, a majority of Americans, by a margin of 54 to 42 percent, trust President Barack Obama over Republicans in Congress to handle negotiations over the Iranian nuclear program.

Iran and the P5+1 (U.S., U.K., France, Russia, China and Germany) powers are attempting to reach a final comprehensive nuclear deal by a June 30 deadline. But there have been disagreements over the timetable for sanctions relief for Iran, with the Islamic Republic calling for immediate relief while the U.S. and European allies are calling for a more gradual lifting of the sanctions over time.
