Would North Korea actually go nuclear against South Korea or the U.S.? How real is the danger?

FOX News Radio's Rich Johnson reports from Washington DC:

South Korea's capital of Seoul is just 30 miles from the border; well within the range of North Korea's artillery. Then, there is the sheer size of the North's military.

Col Leighton (ret): "Their 1.2 to 1.8 million man army would be what the South would be confronted with."

But retired Air Force Colonel Cedric Leighton says the more likely scenario is:

Col Leighton (ret): "Small-scale attacks to test the resolve of the South Koreans."

That's something Pyongyang has done before, like the sinking of a South Korean warship three years ago that killed 46 sailors.
