Poll: Americans want a quick end to Iran conflict and oppose regime remaining in power

A CBS News/YouGov poll of 3,335 U.S. adults (Mar 17–20, 2026) finds Americans want Iran’s nuclear program halted, the Iranian people freed, and deem it unacceptable to end the conflict with the regime still in power. They want the war to end quickly, but rising gas prices and concerns about the economy temper optimism, with many viewing the action as a war of choice and calling for more explanation from the Trump administration. Views on duration vary, and disapproval grows as the conflict drags on, while MAGA Republicans broadly back the president.
