Majority of Americans Expect Large-Scale U.S. Ground Action in Iran, Few Support It

A national poll of 1,545 U.S. adults finds 65% believe President Trump will order a large-scale ground war in Iran, while only 7% back such an outcome. The survey shows public approval of the war and presidential standing remain mixed, with notable partisan divides on strikes and limited special forces deployments. Proposed military options under consideration by the administration include securing tanker routes and operations near Iran's oil infrastructure.

Key Points

  • 65% of Americans believe President Trump will order a large-scale ground war in Iran, while only 7% support such action.
  • The president's approval rating in the survey is 40%, up 1 percentage point from a survey taken in the hours after the U.S. and Israel attacked Iran on February 28; the poll sampled 1,545 adults with a margin of error of about 3 percentage points.
  • Potential military options under consideration include protecting oil tanker transit through the Strait of Hormuz and operations near Iran's shoreline and Kharg Island - implications for energy, shipping, and defense sectors.

WASHINGTON - A recent national poll that closed on Thursday indicates a clear disconnect between public expectation and public support regarding a potential U.S. ground campaign in Iran. Some 65% of respondents said they believe President Trump will order U.S. troops into a large-scale ground war in Iran, yet just 7% said they would support that scenario.

The survey sampled 1,545 adults across the United States and carries a margin of error of about 3 percentage points. The president's overall standing in the poll remained effectively steady at 40%, a one percentage point rise compared with a separate survey taken in the hours after the U.S. and Israel attacked Iran on February 28.

Officials in the administration have considered a range of military options to bolster U.S. operations in the Middle East. Discussions have included deploying thousands of troops to reinforce current forces, using air and naval assets to protect the passage of oil tankers through the Strait of Hormuz, and placing forces along Iran's shoreline. One option under consideration would focus on Kharg Island, which handles roughly 90% of Iran's oil exports.

The poll reveals a pronounced partisan split in attitudes toward recent military actions. Seventy-seven percent of Republicans said they approve of U.S. strikes on Iran, compared with 6% of Democrats and 28% of independents. Overall approval of the war stood at 37%, while 59% of respondents disapproved. The disapproval total includes about one in five Republicans.

On the narrower question of limited deployments, the survey found 63% of Republicans - and 34% of all respondents - would back sending a small number of special forces to Iran. Still, a majority of respondents across the electorate expressed resistance to ground operations: 55% said they opposed deploying any ground troops, whether on a large or small scale.

The responses capture public unease with expanded military engagement even as many Americans anticipate further escalation. The poll's methodological details indicate a broad national sample and the stated margin of error, but do not resolve the political and economic uncertainties that such possible deployments could raise.

Risks

  • Escalation risk: Consideration of deploying troops and securing tanker routes could heighten geopolitical tensions, creating uncertainty for energy and shipping markets.
  • Public opposition and political risk: Majority opposition to ground troop deployments could affect domestic political dynamics and defense policy decisions.
  • Market sensitivity: Potential operations around Kharg Island, which accounts for about 90% of Iran's oil exports, could impact oil supply perceptions and energy-sector volatility.
