BBC News - North Korean border guard 'shoots three Chinese dead'
Is North Korea so close to the brink that they just don't care at this point, or is it still all political gamesmanship. At this point I don't think I would be shocked if they tried a land grab irrationally rationalizing:
a) they could get to Seoul with the element of surprise.
b) china would defend their airspace if push came to shove
c) as a last resort they have the threat of nuking Japan if we intervene.
Granted they have been nearly all bark for the last decade, but is it possible at some point their dear leader just puts all his cards in and goes for it?
