NK desperately wants to get China so scared of impending war they'll beef up NK as a precaution, which will drastically stabilize the current governement's standing and resources.
NK doesn't want war; any winner will be sick of their nonsense and replace the Kim regime.
China doesn't want war, as 100,000 refugees is, for some reason, the straw that kills the camel in a country of 2.5 billion (or whatever it's up to now. I think this refugee thing is a longstanding fear from the fifties when such an influx would have actually destabilized Mao's regime. Nowadays, it would merely be a massive cost to the government).
The US/SK don't want to take over NK, since integrating that country from the stone-age to modern standards would ruin the economies of both. Neither the US nor the Chinese want eachother's troops mustered against the same border; total recipe for WWIII.
So why the saber rattling? It's the only way for the North to get what it wants; more money, modern equipment, better Chinese backing (the PRC has been getting on bad terms with DPRK after this latest bomb test; what NK wants now is for China to circle their wagons around them and once again guarantee protection and support of the Kim regime), and renewed legitimacy for their military leadership. Hostages could only get them a photo-op with Bill Clinton, so now they're upping the ante. And we've obliged by deploying strategic bombers :banghead:
If the North were to commit, it would be suicide. Meaning that if they did so, they would not seek to claim territory, but to inflict as many casulties on SK and US forces as possible. As well as to settle the long-standing grudge with Japan. They would likely fire artillery and rockets in all directions and rapidly conflagrate the whole damn area--it would be far from over quickly. But this all becomes moot when the DPRK develops an ICBM, which they will if their government remains in power for another few years. Before, we marginalized them because we could not invade; with an ICBM we would have to
accept their foul little dictatorship.
There would be tens of thousands of casualties in Soul, probably within 48 hours of the war.
Try hundreds of thousands, if not millions. Dense cities, tall buildings, and 50,000 artillery rounds pre-zeroed with a list of targets. The South could not possibly act fast enough to prevent this devastation. The North has had a tactical nuke aimed at Seoul for fifty years now, and the South has refused to move the city as an act of defiance.
