A large majority of Americans believe that preventing Iran from obtaining nuclear weapons is essential to U.S. national security, according to a new poll released by the Ronald Reagan Institute.
Eighty-four percent of respondents in the survey identified Iran’s nuclear ambitions as a key threat to U.S. security and prosperity—ranking it the top concern among several global issues. The findings were first shared with Fox News on Tuesday.
The results come as President Donald Trump reiterated his stance on the issue, stating this week, “IRAN CAN NOT HAVE A NUCLEAR WEAPON.” His comment follows reports that his administration is weighing U.S. involvement in Israel’s ongoing strikes against Iran, which began last week under the name “Operation Rising Lion.”
That operation targeted Iranian military leaders and elements of the country’s nuclear program. The Iranian regime has responded with daily retaliatory strikes, escalating tensions in the region.
The Reagan Institute poll, conducted from May 22 to June 2—prior to the launch of Israel’s offensive—also found 45% of Americans would support Israeli airstrikes against Iran’s nuclear facilities if diplomatic talks with Tehran collapse. Thirty-seven percent said they would oppose such action, while 18% remained unsure.
A partisan divide emerged in the results: 60% of Republicans backed the potential strikes, compared to 35% of independents and 32% of Democrats. Opposition was highest among Democrats, with just over half against the airstrikes.
Other national security concerns cited by respondents included the potential for war between China and Taiwan (75%), illegal immigration at the U.S. southern border (74%), the ongoing conflict in Ukraine (73%), the security of Israel (71%), and the use of tariffs to advance trade deals (69%).
