Americans Feel More Certain Another 9/11 is Looming

The number of Americans who consider another attack on the scale of September 11, 2001 Very Likely is at its highest level since before the killing of Osama bin Laden. But even though the radical Islamic group ISIS continues to make big threats against the United States from the Middle East, Americans still fear an attack from within more than one from outside.

A new Rasmussen Reports national telephone survey finds that two-out-of-three American Adults (67%) think it is at least somewhat likely that another 9/11 will take place in the next 10 years, including 34% who consider it Very Likely. The latter figure is up from 30% a year ago and the highest finding since 2010 when 39% felt another major attack was Very Likely. Bin Laden was killed the following May, and concern dropped somewhat. But only 20% of Americans think a similar attack is unlikely in the next decade, with just three percent (3%) who consider it Not At All Likely. Thirteen percent (13%) are undecided.
