The SK Air Force is well equipped with F-15s and F-16s that would shoot the shit out of anything Pyongyang can put in the air. Their army is nothing to sneeze at either, nearly half a million troops, 2,400 tanks, 2,700 armored fighting vehicles, 5,800 artillery pieces, 60 guided missile systems, and 600 helicopters, more or less.

And how much such stuff does China have?
I doubt that China would lift one finger to help their (ahem) ‘friends’ in Pyongyang. North Korea has become a liability more than an asset to them. They actually have better relations with South Korea than the North.
I don’t think that bodes well for Kim Jong Un.
