Hey Granny,
I'm male, American, 27, married to a Korean-American woman.
When it comes to the ROK, there are a couple ways of looking at it. For one, it's likely the north has about 22 kg of fissionable material. Based on what I've seen that means about 8 bombs, each of which could have roughly 1-150k killing power.
On the other hand their entire military budget is roughly equivalent to most large American police departments, and they currently have no allies, save perhaps Russia, although they'd be stupid to make overt efforts.
I suspect it's posturing, and if the Western units make a military concession things may die down a bit. The trick is getting America to "negotiate with them thar terrristz".
In either case I'd rather land a uni gig in China. If I cant make that happen, I can get a resident visa and teach privates in the countryside and live with my in-laws. Or just soldier on in a job I hate here in the US.
