US scientist warns against hyping N. Korea threat

The world should take the threat from North Korea's apparent uranium enrichment program seriously but should not hype it, the US nuclear scientist who saw hundreds of centrifuges there said Tuesday.

The scientist, Stanford University's Siegfried Hecker, told a briefing if the North wanted fissile material for bombs it would have made more sense for it to reactivate its plutonium-based program rather than pursue uranium enrichment. (Reuters)
