Americans Favor Deal with Iran; Willing to Back with Force

<a href="/sites/default/files/AmericansonIran_0.jpg" target="_blank">View larger</a>According to the 2015 Chicago Council Survey, fielded between May 25 and June 17, a majority of Americans support the outlines of a nuclear agreement with Iran when it is described as a tradeoff between the United States easing some economic sanctions against Iran, and Iran limiting its nuclear enrichment and development, increasing access to international inspectors, and extending the breakout time to develop a nuclear weapon (59%). Just over a third (36%) oppose the agreement. 

If Iran “commits a major violation of this agreement,” solid majorities would support the United States imposing tighter economic sanctions on Iran (80%) and continuing diplomatic efforts (71%).

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 said they would support “the use of US troops to stop Iran from obtaining nuclear weapons” (67%), on par with opinion in 2014. If Iran violates the agreement, majorities would support the United States conducting cyber-attacks against Iran’s computer systems (60%) and airstrikes against Iran’s nuclear facilities (56%). Fewer support sending US troops to destroy Iran’s nuclear facilities (44% support, 51% oppose).

About

The Chicago Council on Global Affairs highlights critical shifts in American public thinking on US foreign policy through public opinion surveys and research conducted under the Lester Crown Center on US Foreign Policy. 

The annual Chicago Council Survey, first conducted in 1974, is a valuable resource for policymakers, academics, media, and the general public. The Council also surveys American leaders in government, business, academia, think tanks, and religious organizations biennially to compare trends in their thinking with overall trends. And collaborating with partner organizations, the survey team periodically conducts parallel surveys of public opinion in other regions of the world to compare with US public opinion. 

The Running Numbers blog features regular commentary and analysis from the Council’s public opinion and US foreign policy research team, including a series of flash polls of a select group of foreign policy experts to assess their opinions on critical foreign policy topics driving the news.
