Yep, right on cue Kim Jong Il decides to recalibrate the attention factor back towards the Korean peninsula. Given the sorry state that country has been in since losing that Old Russian Cloak, it's an amazing show of gall. Last 2 wars in Iraq were cold buckets of water in the face of regimes like North Korea. I'm sure that pudgy lil bastard has nightmares in 'munition transmission format.' "TLAM! Nooorrrrr11!!!
I hear a lot of people giving props to the South Korean military, and that's a good thing. ROKs are badass, make no mistake. South Korea is a land of cutting edge technology too, this alone counts for a lot when added to their progressive views on military tactics (robotics, etc) Their military is modern, well trained and motivated. Trained reserves are beefy as well.
As many have already noted, the sheer number of huge bore artillery pieces pointing at Seoul is the main issue here. Whooole lot of people gonna die. The US presence at the Korean DMZ is one similar to the one maintained in Germany, i.e. 'the speed bump that gives you the excuse to go full-throttle' concept. I forget the actual DoD estimate, but the time it would take to level Seoul is measured in minutes I believe, and that's just with normal munitions. If a regime tests brews of chemical and biological agents on political prisoners, then you can pretty much expect a version of their use if this regime ever feels like "it's now or never."
The NKs are hard people. Unless you're talking about a select few, NKs get by without amenities most of us couldn't live without (food being just one) and know scarcity and hardship every day of their lives.
Then some of them train for war and are psychologically groomed to fight with the utmost hate.
Yes their tanks are outdated, yes they aren't equipped like our guys, but remember that it's the man before the weapon, not the other way around.
If it comes to war I don't think it will be a cake walk like some are guessing. Far from it, in fact even in the best case scenario (short of a coup anyway) where the UN actually would stand up and just say "look, you have to go" and gets unanimous support (i.e, China and Russia pitching in) I still think it would be a hard fight. That country has been in a state of constant fortification enhancing and preparation. Even with their meager military budget that says something. It's population is kept mind washed and locked up, and in a constant state of fear over invasion. And then there's Stalin's popular "Quantity has a quality of it's own" aspect to it all. Yikes.
I hope this is the just the little man throwing another tantrum, but part of me thinks we're due a naval encounter any day now so Kim can underscore his point to the world. I fear that Kim, famous for his tastes in all things Western, has been paying attention and noticed that we have anti-mortar technology being deployed. He knows, or has been told anyway, that it's only a matter of time before the same concept is tweaked and improved thus making it effective with artillery. Combined with the surgical strikes the US is now famous for (depending on who you talked to I suppose) it could mean Kim won't have the Seoul Hand to play, or least not all of it. This is where things get scary...
