HONOLULU (AP) — The United States is reviewing whether to put North Korea back onto its list of state sponsors of terrorism, President Barack Obama said as the U.S. decides how to respond to the cyberattack on Sony Pictures Entertainment that law enforcement has blamed on the communist nation.

 Obama described the hacking case as a "very costly, very expensive" example of cybervandalism, but did not call it an act of war. In trying to fashion a proportionate response, the president said the U.S. would examine the facts to determine whether North Korea should find itself back on the terrorism sponsors list. 
  
 "We're going to review those through a process that's already in place," Obama told CNN's "State of the Union" in an interview to air Sunday. "I'll wait to review what the findings are." 
  
 North Korea spent two decades on the list until the Bush administration removed it in 2008 during nuclear negotiations. Some lawmakers have called for the designation to be restored following the hack that led Sony to cancel the release of a big-budget film that North Korea found offensive. 
  
 Only Iran, Sudan, Syria and Cuba remain on the list, which triggers sanctions that limit U.S. aid, defense exports and certain financial transactions. 
  
 But adding North Korea back could be difficult. To meet the criteria, the State Department must determine that a country has repeatedly supported acts of international terrorism, a definition that traditionally has referred to violent, physical attacks rather than hacking. 
  
 Obama also leveled fresh criticism against Sony over its decision to shelve "The Interview," despite the company's insistence that its hand was forced after movie theaters refused to show it. 
  
 While professing sympathy for Sony's situation, Obama suggested he might have been able to help address the problem if given the chance. 
  
 "You know, had they talked to me directly about this decision, I might have called the movie theater chains and distributors and asked them what that story was," Obama said. 
  
 Sony's CEO has disputed that the company never reached out, saying he spoke to a senior White House adviser about the situation before Sony announced the decision. White House officials said Sony did discuss cybersecurity with the federal government, but that the White House was never consulted on the decision not to distribute the film. 
  
 "Sometimes this is a matter of setting a tone and being very clear that we're not going to be intimidated by some, you know, cyberhackers," Obama said. "And I expect all of us to remember that and operate on that basis going forward." 
  
 North Korea has denied hacking the studio, and on Saturday proposed a joint investigation with the U.S. to determine the true culprit. The White House rejected the idea and said it was confident North Korea was responsible. 
  
 But the next decision — how to respond — is hanging over the president as he vacations with his family in Hawaii. 
  
 Obama's options are limited. The U.S. already has trade penalties in place and there is no appetite for military action.

 Washington (CNN) President Barack Obama says he doesn't consider North Korea's hack of Sony Pictures "an act of war." 
  
 "It was an act of cybervandalism," Obama said in an interview with CNN's Candy Crowley that aired Sunday on "State of the Union." 
  
 Obama said that the United States is going review whether to put North Korea back on a list of states that sponsor terrorism. 
  
 "We've got very clear criteria as to what it means for a state to sponsor terrorism. And we don't make those judgments just based on the news of the day," he said. "We look systematically at what's been done and based on those facts, we'll make those determinations in the future." 
  
 The President stuck by his criticism of Sony's decision to cancel its plans to release the movie "The Interview," which includes a cartoonish depiction of the assassination of North Korean leader Kim Jong Un, after the country threatened attacks against theaters that showed it. |||||

With the FBI confirming that North Korea was behind the Sony hack, President Obama tells CNN in an interview airing today that "it was an act of cyber vandalism that was very costly, very expensive," not "an act of war." Nevertheless, he says that the US is reviewing whether to throw Pyongyang back on the list of state sponsors of terror. "I'll wait to review what the findings are," he says. That could be dicey: The AP notes that it requires the State Department to blame Korea for terror under "a definition that traditionally has referred to violent, physical attacks rather than hacking." North Korea had spent two decades on the list until the Bush administration removed it in 2008; only Cuba, Iran, Sudan, and Syria remain. Other highlights from the interview this morning on State of the Union: On Sony's decision to pull the plug on The Interview: "I was pretty sympathetic to the fact that they have business considerations that they got to make. Had they talked to me directly about this decision, I might have called the movie theater chains and distributors and asked them what the story was." On setting a dangerous precedent: If "a dictator in another country can disrupt through cyber, a company's distribution chain or its products, and as a consequence we start censoring ourselves, that's a problem. ... This is a matter of setting a tone and being very clear that we're not going to be intimidated by some cyberhackers. And I expect all of us to remember that and operate on that basis going forward." Because it doesn't stop there: "And it's a problem not just for the entertainment industry, it's a problem for the news industry. CNN has done critical stories about North Korea. What happens if in fact there is a breach in CNN's cyberspace? Are we going to suddenly say, are we not going to report on North Korea?"
