No worries Sonny, china is at risk from NK as well; some of china's territory is coveted by nk from what I've read. The POTUS I doubt thinks much about little kim and his delusions, although I'm certain many in the employ of the US keep a Very close watch on NK. Russia I think is just biding their time. While much has been made about Ukraine (and should be) the area's under russian control are inhabited by, well, russians. Not to say that should unrest happen elsewhere in the world the russian border wouldn't expand a little more (sort of a, "Hey, look over there" move)I'd be much more worried about the enemies that obama armed with nukes. With the eu overrun by an invading army and little justin opening the border here, well, I'd be more worried about a suitcase than an NK missle.But then that's just me.
I think some covert mission has to happen within NK and take out or severely hamper their nuke programs.
How long can a rouge nation with Nuke capability keep poking the bear(any western country). .
I would say as long as your big friend allows you too. Not to many Western Nations want to go to any kind of war with China. Whether that be sticks and stones or nukes. Hence, why most Western Nations spend most of there attention on persuading China to do the right thing and basically ignore what comes out of North Korea. What Kim Jong-un says is irrelevant and reaction to what he says is just a soap box for him which is what he wanted in the first place.
