A new Harvard CAPS/Harris Poll revealed widespread support among American voters for President Donald Trump's approach to the ongoing conflict with Iran, including military strikes and a naval blockade.

The survey, conducted online April 23-26 among 2,745 registered voters, found that 74% believe the United States is winning the conflict over Iran. Additionally, 52% supported U.S. military airstrikes on Iran, with 54% saying those strikes were justified. A strong 78% approved of Trump's decision to agree to a temporary ceasefire, and 57% backed the imposition of a blockade on ships heading to Iran.

Support extended to key strategic goals. Seventy-four percent agreed it is in America's interest to prevent Iran from obtaining a nuclear weapon, while 79% said Iran must stop supporting proxy groups like Hezbollah and Hamas. Sixty-three percent favored maintaining the blockade if Iran refuses to abandon its nuclear ambitions, and 66% supported creating a multinational naval force to secure the Strait of Hormuz.

Views showed some bipartisan consensus on core issues. For instance, 60% of Democrats, 91% of Republicans, and 70% of independents said stopping Iran's nuclear program serves U.S. interests. On whether the ceasefire was the right move, 76% of Democrats, 85% of Republicans, and 75% of independents agreed. However, partisan divides appeared on the blockade, with 86% Republican approval compared to 36% among Democrats.

The poll comes amid heightened tensions in the U.S.-Iran conflict that began earlier this year. Following failed negotiations and Israeli strikes, the U.S. imposed a blockade on the Strait of Hormuz and conducted airstrikes. Recent ceasefire talks brokered by Pakistan faltered, with Trump expressing dissatisfaction over Iran's latest proposal on April 28. Iranian officials described their army as still in a "war situation" as the blockade persists.

Sixty-seven percent of voters view Iran as a leading source of instability, terrorism, and war in the Middle East, and 65% consider it a national security threat to the U.S. A majority, 64%, believe Iranian leadership has fractured into factions, potentially weakening Tehran's position.

While the poll indicated broad endorsement for specific measures, overall approval of Trump's handling of the Iran conflict stood at 39%, reflecting concerns over related economic pressures like rising gas prices. Trump's general approval rating dipped to 42%.
