Think it's obvious Korea would like to be unified as soon as possible.
But South Korea will never let any foreign power attack NK, not from its own territory at any rate.
you need to attack from SK - plus i am sure SK will be convinced to fight against NK if any country was to go to war with NK,
numbers mean nothin, 1.2million might sound a lot but pretty pointless if you are economically unsustainable. All countries around the world have already talked about sanctions against NK. NK need not be defeated militiarically they can easily be defeated economically they depend highly upon aid.
At last resort NK will then have to threaten or invade a nearby country for resources when this happens.. i am sure they be attack and obliterated. Unlike IRaq or afghanistan there is little interest for other countries to preserve NK (like no oil etc).
military NK are weak compared to neighbours. china, india, pakistan, and of course russia. Japan are i think have militaric restrictions on them by the USA - nevertheless they have full support of them.
NK cannot win against the world - Asia is becoming more and more important globally economically as a result it is in the interests of the rest of the world at all costs to maintain stability there. China and India re two fastest growing economies .. relative terms, both have been boasted to be superpowers inthe future both have large militarys and advanced technologies.
