Six in 10 Americans Support US Participation in a Nuclear Agreement with Iran.

Chicago Council on Global Affairs, 30 Apr 25

Majorities of Democrats and Independents support a potential deal similar to the 2015 Joint Comprehensive Plan of Action, but only a minority of Republicans agree.

For the first time since the United States withdrew from the 2015 Joint Comprehensive Plan of Action (JCPOA), American and Iranian officials held direct talks to negotiate a new nuclear deal. These talks come amid reports of Iran’s rapid production of enriched uranium and acceleration of its nuclear weapons program.

A recent Chicago Council on Global Affairs-Ipsos survey, fielded April 18–20, 2025, finds a majority of Americans consider a nuclearized Iran unacceptable and believe the United States should negotiate a deal with Tehran to limit its development. While Democrats and Independents support a deal that would trade sanctions relief for limitations on Iranian nuclear enrichment, Republicans oppose such a tradeoff. However, they may end up following US President Donald Trump’s lead if current negotiations bear fruit.

Key Findings

Eight in 10 Americans oppose Iran obtaining nuclear weapons (79%) and favor taking diplomatic steps (83%) or tightening economic sanctions (80%) to limit further nuclear enrichment.
A smaller majority of Americans believe the United States should participate in an agreement that lifts some international economic sanctions against Iran in exchange for strict limits on its nuclear program (61%).
Partisan differences on a nuclear agreement are striking: 78 percent of Democrats and 62 percent of Independents support US participation in a deal with Iran compared to just 40 percent of Republicans.
If diplomacy or economic sanctions fail, many Americans are willing to take more forceful approaches: Six in 10 support the United States conducting cyberattacks against Iranian computer systems (59%), and half support conducting airstrikes against Iran’s nuclear facilities (48%).
A majority oppose sending US troops to destroy Iran’s nuclear facilities (60%).

Americans Favor Diplomatic Approach to Iranian Nuclear Development

The 2015 JCPOA, or the Iran Deal, was a landmark agreement reached between Iran and the P5+1 (China, France, Russia, the United Kingdom, the United States, and Germany) that limited Iranian nuclear enrichment in exchange for sanctions relief and other provisions. While it was initially successful in limiting Iran’s stockpile of enriched uranium, the United States withdrew from the deal in 2018, as the first Trump administration considered it insufficient in curbing Iran’s ballistic missile program and protecting American regional interests. Upon the US withdrawal from the agreement, Iran promptly lifted the cap on its stockpile of uranium and increased its enrichment activities; it has since reached weapons-grade levels of enriched uranium.

…………………………………………………………………………………………………………………………………………………………………… Conclusion

Although US President Donald Trump has not ruled out using military action to stop Iran from obtaining a nuclear weapon, he said he favors a diplomatic agreement to address this issue. Recently, Trump administration officials have given contradictory remarks about current talks, and they have yet to specify how renewed negotiations will produce an agreement more stringent and impactful than its predecessor.

The pressure is on American diplomats to secure a deal that would limit Tehran’s nuclear enrichment without providing the sanctions relief that could potentially fund Iran’s efforts to further destabilize the Middle East or threaten the United States’ regional allies, including Israel. While the outcome of these negotiations remains to be seen, the public continues to express a preference for using diplomatic or economic coercion than direct military action. https://globalaffairs.org/research/public-opinion-survey/six-10-americans-support-us-participation-nuclear-agreement-iran?fbclid=IwY2xjawKA64xleHRuA2FlbQIxMQBicmlkETFISGV5ZEdSZW16a2ZnQzh3AR7iwwVkEnczI_DJHzOGHWvNWeSlg2xdd9YJCsBz0_OiQmJcM48Ujd0ZNX8ZNQ_aem_5kroZ8t3KQ5RgYf4EfYdDA
