Time: As nuclear negotiations with Iran resume in Geneva today, a new poll by the Washington Post and ABC News finds the majority of Americans would support an agreement between major world powers and Iran that would scale back its nuclear program in exchange for relief from economic sanctions.

64 percent of the 1,006 adults polled by Abt-SRBI between Nov. 14-17 said they would support an agreement between Iran and the six major world powers—meeting in Geneva today — that would ease some of the economic sanctions against the Islamic Republic in return for restrictions on its ability to produce nuclear weapons. 30 percent of the respondents said they would oppose the agreement.

But when asked how assured they were that the agreement would actually prevent Iran from developing the weapons, only 36 percent were either somewhat or very confident, while 61 percent were more pessimistic.
