So the yanks managed to sneak into North Korea. Sneak past NK security at their big nuclear testing mountain thing. Explode a couple of enormous bombs (carried presumably in their rucksacks) to collapse the mountain and sneak out again. They'll have used the old 'becoming invisible' juice I've seen in Bond films then.
I mean, I enjoy Red's posts as much as the next man but you do realise he isn't actually a member, ex or otherwise, of some clandestine military unit with super-natural powers? He's an old tosser that served in the British Army in Germany, set up home there when he was discharged (honourably) and did alright for himself. Very good with dogs I reckon.
