I think the NK saga is great fun to observe - mainly because the US tends to make a habit of attacking countries that are technically 'lower' down the military-tech ladder than themselves.
Whereas NK, with nukes - means the US is facing up against a country on roughly the same playing field. And this is something that - despite all the gung-ho macho stuff - that the US has never (not since WW2) had to deal with. So the US can't do its normal thing of rattling big weapons and riding in to attack, which they've been doing in whatever country they fancy - safe in the knowledge that they can't be hit back at too easily. While NK may not have long range ballistic weapons - they do have a lot of submarines, which themselves, are capable of missile launching.. and the Pacific does stretch all the way from Korea/Japan - up to the West coast of the US.. so it doesnt have to be about the firing of missiles from NK itself..
I think the UN is in an emergency session, followed by some sort of address by Bush on the NK issue.. not that the US (I believe) will dare to do anything 'tangible' - the ball is firmly in the court of NK.. not a bad teaching lesson to the US, who've gotten way too used to the idea that conventional enemies can be overflown, bombed, then invaded and occupied.. (to see where THAT ends up, do a search for a recent movie documentary called 'the war tapes' - where they gave a bunch of Iraq-headed soldiers, cameras to film what they saw. That shows the reality of Iraq and the US involvement from a firstperson perspective.)
