Nearly three-quarters of Americans don’t believe President Barack Obama’s assertion that the country won’t use ground troops to fight the militant group Islamic State in Iraq or Syria, the latest Wall Street Journal/NBC News/Annenberg survey finds.

The poll shows a substantial lack of trust in Mr. Obama’s repeated assertions that American military efforts will be limited to airstrikes and other efforts that don’t include ground troops. Some 72% of registered voters surveyed said U.S. ground troops eventually will be deployed against Islamic State’s fighters. Only 20% said they believe the U.S. won’t end up using military ground forces.

The Obama administration has cautioned that the battle against Islamic State won’t be won quickly. It has said it will proceed with an international coalition and that the U.S. won’t commit ground troops to combat.

“I want to be clear: The American forces that have been deployed to Iraq do not and won’t have a combat mission,” Mr. Obama said Sept. 17. “As your commander in chief, I won’t commit you and the rest of our armed forces to fighting another ground war in Iraq.”
