- Six in ten Americans (59 percent) favor the framework of an agreement with Iran.
- Seven in ten (67 percent) support using U.S. troops to stop Iran from obtaining nuclear weapons.
- Nearly six in ten (56 percent) support U.S. airstrikes against Iranian nuclear facilities if Iran violates the deal.

- At the same time, in principle, Americans seem willing to use force to prevent Iran from obtaining a nuclear weapon. Before any mention of the current negotiations with Iran in the survey, two in three Americans say they would support “the use of U.S. troops to stop Iran from obtaining nuclear weapons” (67 percent). If Iran violates the agreement, majorities would support the United States conducting cyber-attacks against Iran’s computer systems (60 percent) and airstrikes against Iran’s nuclear facilities (56 percent). Fewer support sending U.S. troops to destroy Iran’s nuclear facilities (44 percent support, 51 percent oppose).
Majority of Americans Label Iran’s Nuclear Program a Critical Threat
- The public rates the possibility of unfriendly countries becoming nuclear powers (59 percent) and specifically Iran’s nuclear program (57 percent) among the seven most critical threats facing the United States. In addition, nearly eight in ten Americans say that Iran plays a somewhat negative (44 percent) or very negative (33 percent) role in the Middle East today.
Questions about Lasting Impact of a Nuclear Deal
- Only three in ten Americans are confident that the agreement will prevent Iran from developing nuclear weapons in the next ten years (29 percent; 69 percent are not). Even those who support the agreement with Iran tend to doubt its ability to prevent Iran from developing a nuclear weapon in ten years (42 percent of deal supporters versus 9 percent of those who oppose the deal).
Partisan Differences on Deal, but Shared Support for Action if Iran Violates
- A solid majority of Democrats (74 percent) and a smaller majority of Independents (57 percent) favor the nuclear deal, while Republicans tend to oppose it (51 percent, 46 percent support). Likewise, Democrats (41 percent) are more confident than Republicans (16 percent) or Independents (26 percent) that the deal will prevent Iran from acquiring nuclear weapons in the next decade.
- While majorities across political parties support using U.S. troops to stop Iran from obtaining nuclear weapons, only among Republicans do a majority (53 percent) favor sending U.S. troops to destroy Iran’s nuclear facilities if Iran commits a violation of the accord (53 percent versus 44 percent of Democrats and 37 percent of Independents).
About the Chicago Council Survey
The analysis in this report is based on data from the 2015 Chicago Council Survey of the American public on foreign policy. The 2015 Chicago Council Survey was conducted by GfK Custom Research using their large-scale, nationwide online research KnowledgePanel between May 25 and June 17, 2015 among a national sample of 2,034 adults, 18 years of age or older, living in all 50 US states and the District of Columbia. The margin of error ranges from ± 2.2 to ± 3.1 percentage points depending on the specific question, with higher margins of error for partisan subgroups.
The 2015 Chicago Council Survey is made possible by the generous support of the John D. and Catherine T. MacArthur Foundation, the Robert R. McCormick Foundation, the Korea Foundation, the United States-Japan Foundation and the personal support of Lester Crown and the Crown family.
