North Korea posted a strange video about an attack on New York City, accompanied by the tune 'We are the World.' Why you shouldn't worry.
First, North Korea doesn't have a space shuttle (or the capability to launch one), as the video portrays in a boy's dream.
Second, North Korean doesn't yet have the capability to reach the US with one of their Unha rockets, let alone New York City.
As The Christian Science Monitor reported recently: "Concerns about their missile tests are overblown, according to RAND analyst Markus Schiller in a lengthy 2012 report on North Korea’s missile programs.
“Every launch further depletes the limited North Korean arsenals, and North Korea gains no real experience from these events. Since the purpose of the launches seems to be political, the United States and other nations should downplay or even ignore them,” he writes.
