Siegfried S. Hecker

And you had countries like Japan and South Korea saying, ah, they can't build a bomb.

Siegfried Hecker was one of the invited scientists.

They were in a conference room and they brought in a red metal box opened that up, and inside was a white wooden box with a slide off top.

They opened that up, and inside were two glass jars, sort of like jelly jars, with a screw-on lid, tightly taped.

Given their past behavior, given the belligerent manner in which they are constantly threatening their neighbors, I don't think there's any question that that would be a destabilizing situation.

In November 2010, the North Koreans went on the front foot to showcase their nuclear might.

US nuclear scientist, Siegfried Hecker, was invited back to visit their facility, which now had 2,000 centrifuges.

My jaw just dropped.
