One thing you didn't mention in your presentation is China. You spoke about the maritime component of NORAD. I know that China is aggressively developing the blue-water fleet and also the submarine fleet. As you've said, submarines probably can be a very great threat now. Submarine warfare can be undertaken in a completely new way, modernized from the former U-boats that were used in the Second World War.
Is it the intention of China to eventually cooperate with Russia?
