No fly zones are useless against a balistic first strike, the most likely scenario from NK. The no fly zone will just starve out NK more, and force the little madman to jump. That is, if China lets go of his leash.
Gotta time the NK blowup to sync with the ME blowup or the effect on the USA will be unduely limited.
Korea and Taiwan are pawns in the Red Chinese chess game. The prize is the Queen, Washington, because China sees Europe as a gelded King. Once China breaks the US, it is checkmate on Europe.
The reasoning behind No Fly Zone is that, at current stage, N. Korean nuke could be only delivered via airplane.
About the chess game, I agree with your general thrust.
A recent series of articles on the net margins that the past massive detonation on North Korea's rail waypoint to China,
saw numerous Syrian technicals blown to Allah.
Clearly...China is spiteing the U.S. in this matter....beyond the N.K. nuclear gambit.
One wonders if their is an underground rail net between the 2 nations
I've read some posturing that U.S. is soon to hit China with new sanctions over their missile proliferation.
Likely...China will tantraum and claw back thru other paths.
I imagine if the U.S. went on China with sanctions over M.P. and trade violation,
it would probably walk both to wars doorstep.
Money and caressing.
Its lika a visit to the White Tiger...
