Nearly 6 in 10 Americans disapprove of the US decision to take military action in Iran, as most say a long-term military conflict between the two nations is likely, according to a new CNN poll conducted by SSRS.

Most, 54%, say Iran will become more of a threat to the US as a result of this military action, with just 28% saying the strikes will make Iran less of a threat.

The CNN poll was conducted by SSRS on February 28 and March 1. Interviews with 1,004 adults nationwide were conducted by text message. People interviewed for the poll are members of the nationally representative SSRS Text Message Panel. Results for the full sample have a margin of sampling error of plus or minus 3.9 percentage points.
