Missile experts see Soviet parts in NKorean rocket

But the scientists say that if North Korea does have such a Russian-made ballistic missile in its arsenal, it could modify the rocket into a two-stage missile that could reach Seattle, Wash., carrying a 900-kilogram warhead, or San Francisco carrying a 700-kilogram charge.

900kg = 1985 lbs. 1 ton, general considered sufficient for a nuclear warhead.
Maybe the 4th in Seattle we’ll have a real fireworks show!
