"Whilst on a roll,I'm guessing that the North Koreans are next in the queue?"
Purely a personal opinion - I don't believe NK will ever be next on the list.
Look at a map ------------ no mates on the route - only water. Also, China has a lot to say right nearby ---------- this is NOT the 1960's now -------- with China as a neighbour and the holder of a load of US assets ---------- they will not want to interfere.
The US is buggered -------- possibly terminally damaged - another war will see them off probably ---------- a long long over the ocean war with no mates to support on the way would finish them rapidly -------------- they will make a lot of noise about NK, but in the end - they will do nothing.
If their CIA can't do the job on the inside -- it won't be done. And lets face it ---------- the CIA is really showing itself to be like a bull in a china shop. Not quite as stupid as the French secret service being done by a NZ copper, but close.
