I have my doubts that anyone will be able to do much with the North Koreans now. They are too far along - and certainly will be once they miniaturise a warhead - in their ability to respond. Between the ICBMs, IRBMs, MRBMs, Scuds and ballistic missile submarines, what they've effectively done is create a comprehensive second and third strike capability. Take the missile launched yesterday. It wasn't launched from a fixed position like a silo, it was launched from a truck. That makes it 1) mobile and 2) very easy to hide. The North Koreans have plenty available - at least enough to create doubt - and we saw a bunch of these TELs paraded some months ago with a range of missiles on them, including yesterdays. Their success rate for missile tests is also remarkably high from independent estimates - somewhere around 65 to 75 per cent. That creates even more doubt. The other thing going for the North Koreans is the volume of ordnance pointed at Seoul. They have enough to destroy that city in short order, killing millions of people at the same time, and to make military action appear questionable. Now I know taking military action against them seems to be a popular and smart thing to do, but you better hope to hell you have every submarine, launcher, artillery piece, and bomber found and targeted, because if you don't a lot of people are going to die. Instead, I think an Asian - and maybe even global - arms race akin to the build up to World War 2/the Cold War/etc is back on the cards. SIPRI actually shows that global spending on weapons went up 0.4 per cent over the previous 12 months, and I think that will keep increasing over the next decade.
