These new attacks are also contributing to the increasing sense of fear and anger Americans feel when reflecting on 9/11, the CNN/ORC polls finds. Forty percent of Americans said they felt fear and around three-quarters anger when looking back to 9/11. Five years ago, those numbers stood at 62 percent and 30 percent, respectively.
A Pew Research Center poll released Wednesday paints a similar picture. Forty percent of Americans says that the ability of terrorists to strike in the United States is greater than it was on Sept. 11, 2001, and 31 percent believes terrorists' ability to launch an attack are about the same.
In Pew's numbers, there is also a sharp partisan divide in terms of how Americans feel about the liklihood of a major terrorist attack, reflecting an increasingly polarized political landscape during an election year.

Nearly 60 percent of Republicans consider the ability of terrorists to attack as greater than at the time of 9/11, Pew finds, while 34 percent of independents and 31 percent of Democrats felt the same.
"Opinions about terrorists' capabilities to attack the U.S. have long been divided along partisan lines," the center writes. "During George W. Bush's presidency, Democrats were often more likely than Republicans to say the ability to terrorists to launch a major strike was greater than at the time of 9/11, while the reverse has been true during Barack Obama's administration."
"But this marks the first time in the past 14 years that a majority in either party has expressed this view," the report continues.
