Hagel defends US actions

Secretary Chuck Hagel says North Korea's provocative actions and belligerent tone had "ratcheted up the danger" on the Korean peninsula, but he denied that the United States had aggravated the situation by flying stealth bombers to the region. "We have to take seriously every provocative, bellicose word and action that this new young leader has taken so far" since coming to power, referring to Kim Jong-un.
