Fishrrman's credo:
Reality is what it is. It is not what we believe it to be.
It doesn't matter -where- we "base" forces.
That will do nothing to "deter" North Korea from amassing nuclear weapons, from building ICBM's, and from building nuclear-powered submarines which are no doubt intended to carry nuclear-tipped missiles.
The only thing that will physically deter the NORKs at this point, is military action conducted against them.
Or, perhaps, a "grand bargain" with China (but that might involve giving up Taiwan).
