A Rasmussen Reports national telephone survey found that 23% of American voters believe it is Very Likely the U.S. will be at War with Iran within a year. Another 32% believe war is Somewhat Likely. The survey of 800 Likely Voters found that 31% said War was Not Very Likely while just 4% view War as Not at All Likely. These figures are little changed over the past couple of months.

Earlier surveys found that 75% of Americans believe Iran is likely to develop nuclear capabilities in the near future.

The current survey found that 40% believe the United States should use military force to prevent Iran from developing nuclear weapons. Another 40% disagree and say force should not be used. Republicans, by a 2-to-1 margin, favor the use of force. Democrats, by a similar margin, are opposed. Those not affiliated with either major party are fairly evenly divided.

Those figures come at a time when just 30% of Americans believe the President is doing a good or an excellent job handling the situation in Iraq. Americans overwhelmingly prefer to bring troops home from Iraq.

Only 35% believe that diplomatic efforts can succeed in stopping Iran from developing nuclear capabilities. Thirty-seven percent (37%) say diplomatic efforts will not work. A solid plurality of women believes that diplomatic efforts can succeed. A solid plurality of men disagrees.

Eighty-four percent (84%) of American voters have been following news stories about tensions with Iran. That figure includes 48% who have been following the news Very Closely.

Twenty-five percent (25%) of American voters consider Iran the greatest threat to the U.S. national security these days. That ranking has been consistent for several months. North Korea is second at 21%.
