Interesting article on the North Korean missile program, and its connections with the Iranian one.
The Taepodong and the Shabab are basically the same missile. Iran gets theirs to work better; I guess that’s what happens when you aren’t starving your work force.
And Khan is tied in with all this.

I think the North Korean bomb that worked was based on a Khan design, and if that is the case, they might have a design that does fit on a missile.
I doubt the “test” this weekend will involve a bomb, though; Kim wouldn’t want to waste a bomb on a missile that hasn’t been completely successful.
But that’s coming.
