MAD has allowed Russia, China and NK to threaten the World to allow them to do as they please. I'm sure you are aware that China has stolen most of the South China Sea AND GOT AWAY WITH IT. Did MAD deter them? No, it emboldened them. If it will never happen, as you assert (not sure how you know) then surely the concept can be used to push China back and get them out of the islands they stole - or would MAD not work because China does not care? And if China does not care then MAD is not working and so China needs to be dealt with NOW before it becomes unstoppable. Btw, this view was shared, the day after I wrote my first piece, by a top American Military man - he said China has to be stopped now and I guess he knows more about it than me, or any member here. Or shall we keep asking them nicely for the next 20 years, until they have 20 aircraft carriers, 100 subs, have taken over most of the world? And then, after China has been dealt with, we can move on to NK. Only Russia would be the one (under Putin) to avoid conflict with - but that country could well be democratic after Putin and maybe one day a member of NATO (or some World grouping) helping to stabilise the world.
