Reporter: There's been so much talk about a possible missile launch by north korea. More speculation this morning about a possible nuclear show of force. There's an indiacation gnat pyongyang may be plang. In this ongoing provocation, including north korean kim jong-un practicing shooting, the u.S., South kree yarks and japan are prepares just in case north korea could launch another missile. Two missiles were spotted being transported to the coast last week. It could reach the u.S. Base in guam. U.S. Surveillance has not been able to locate them. We don't know where they are. They could be launched at any time, surprising the united states, japan, and south korea as well. Reporter: There are predictions this launch could happen as early as wednesday. But the type of aggressive action is not new. The last rocket test was exactly one year ago. If the next one is aimed into the sea instead of an attack on the country, the u.S. Is unlikely to fire back. It wouldn't necessarily provoke a military response? I'm not going to comment on that.
