Obama says US reviewing whether to return North Korea to list of state sponsors of terrorism

President Barack Obama says the United States is reviewing whether to put North Korea back onto its list of state sponsors of terrorism.

Obama says the high-tech attack against Sony Pictures Entertainment isn't an act of war, but is a very expensive example of cybervandalism. The U.S. blames North Korea for the attack.

Obama tells CNN's "State of the Union" that the U.S. will examine the facts to determine whether North Korea qualifies for the terrorism sponsors list. North Korea was removed in 2008.

Sony has canceled the release of a film that North Korea found offensive. Sony says it had no choice because theaters wouldn't show the film.

But Obama says had Sony spoken to him directly, he might have called the movie theaters to question their decision.
