U.S. troops stationed in South Korea, less than 20 miles from the border with North Korea, bases in Japan and Guam are all targets for North Korea's missiles. Chris Lawrence reports on how and where North Korea would strike U.S. troops.

A former senior US official, who recently retired, says North Korea is a difficult target for the intelligence community but "the coverage is very extensive using national technical means: imagery, intercepts and other means." The official said, "It's hard to get in there, but we do have external capabilities. Looking, listening and watching are all in play."
Moving a missile to the east coast is "very discernible", the official said, even on mobile launchers. The mobile launchers are more difficult–one or two might get through, the official said, but North Korea has limited routes to take whether by rail or road. "It's not a large country with an intricate transportation system."
What is difficult to ascertain is its uranium enrichment program. It could be buried in underground facilities where there are no air samples, nothing to collect.
There are other shortfalls for gathering intelligence on North Korea, in particular a lack of human intelligence, the official said. "We don't have physical access, minimal, if at all," the official said.
As tensions mount on the Korean Peninsula, Wolf Blitzer explains what's behind the threats and what's at stake in a special edition of "The Situation Room," Thursday at 6 p.m. ET on CNN.

Senior U.S. officials tell CNN that at the State Department briefing Thursday, spokeswoman Victoria Nuland is going to try and take the focus on North Korea in a different direction toward diplomacy, as part of an administration-wide effort to calm tensions with North Korea.
The U.S. has been saying its military actions have all been defensive in nature and focused on the U.S. protecting its allies and its homeland. Now Nuland is going to send the message “this is time for diplomacy” and urge North Korea to stop threats and get back on the peace train, one official said.
Nuland is going to be setting up the fact Kerry is in Asia next week and will be talking about “finding a diplomatic way forward,” the official said.

Intercepted communications in recent days indicate that North Korea could be planning to launch a mobile ballistic missile in the coming days or weeks, a U.S. official tells CNN. Previously, South Korean Defense Minister Kim Kwan-jin said that North Korea has moved a medium-range missile to its east coast for an imminent test firing or military drill.
