Most Americans want the U.S. to stop letting in Syrian refugees amid fears of terrorist infiltrations after the Paris attacks.

The findings are part of a Bloomberg Politics National Poll released Wednesday that also shows the nation divided on whether to send U.S. troops to Iraq and Syria to fight the Islamic State, an idea President Obama opposes, and whether the U.S. government is doing enough to protect the homeland from a comparable attack.

Fifty-three percent of U.S. adults in the survey, conducted in the days immediately after the attacks, say the nation should not continue a program to resettle up to 10,000 Syrian refugees. Just 28 percent would keep the program with the screening process as it now exists, while 9 percent said they would favor a limited program to accept only Syrian Christians while excluding Muslims.

Terror in general and specifically the Islamic State, which claimed responsibility for last week’s attacks, are cited by a combined 35 percent of Americans as the top issue in the survey conducted Nov. 15-17.

There is no consensus about whether to send U.S. troops to Iraq and Syria, with 44 percent for the idea and 45 percent against it; or whether the U.S. has done enough to protect the homeland from a Paris-style attack.

The national poll of 1,002 adults was conducted Nov. 15-17, for Bloomberg Politics by Selzer & Co. of Des Moines, Iowa.
