The question is not who would WIN the war, but what the result would be.
NK is pretty much just one giant army. their resources are so low thety actually cannot keep the country powered all at once (they have rolling brownouts). The people have no food.
You would think that teh people would be against this, but many think that they are suffering from what the nations around them are doing, not from their own psycho leader with the horrible fashion sense and sadistic tastes in military march styles.
ANYBODY starts a war with them and half of SK will be wiped out before a standoff is reached. There will be NO guarantee that Russian and/or China will not support NK either openly or under the table.
The only reason we went after Iraq instead of NK in the "axis of evil" is because we thought Iraq would be easy.
The fight was a breeze, it was the cleanuup afterward that is killing us now. Could you imagine how much $$ it would cost to get NK back on track IF "we" were to win?
This is a no win for all parties. I just hope Kim Joong is not illin' enough to actually pull something.
