A recent poll conducted by Quinnipiac University and released on Wednesday, July 30th, 2026, found that 55 percent of Americans believe the ongoing U.S. military operation in Iran will last a year or longer. Of those respondents, 20 percent expect the conflict to last exactly one year, while 35 percent anticipate it will extend beyond 365 days.

The survey also revealed that 34 percent of respondents think the strikes will last for several months, 4 percent expect the conflict to last only weeks, and 1 percent believe fighting will last just days.

Support for the conflict remains limited, with only 34 percent backing the military action and 60 percent opposing it. Opposition is particularly strong among Democrats, with just 5 percent supporting the military efforts, and 26 percent of independents expressing support.

Quinnipiac polling analyst Tim Malloy commented on the findings, stating, “The pushback is evident. Six in 10 voters want no part of military action against Iran.”

This poll marks a significant increase in expectations for a prolonged conflict compared to an April 2026 Quinnipiac survey, where only 32 percent of respondents believed the war would last a year or longer.

The renewed U.S. strikes late Wednesday followed a surprise attack by the Iranian Revolutionary Guard Corps on an American base in Jordan.
