They don't have the range to get to Europe so we're in the clear, no radiation here.He, Kim, was educated in Switzerland apparently and according to the papers here he is perceived as a weak character. What would worry me about that is the people behind him who maybe channelling their agenda.
Im with oldnick on this one....
If Soeul is nuked the downside is there will be a shortage of TV's, ships, cranes, microchips and advanced electronics in general (Samsung is the biggest consumer electronics company in the world).
The fact that Seoul is in a natural bowl and a nuke would wipe it out (remember the 10 million people living there) is also a downside. Oh, and the world wide recession and risk of a bigger war is also of concern.
I don't think it will happen though.
