WE had the Cold War. Now get ready for the Very Cold War. Scotland, military strategists warn, is back on the frontline of a new geopolitical conflict. This time the battle is for control of the arctic, as global warming frees up new shipping passages and opportunities for tourism, oil and underwater mining.  Navy expert Lee Willett of RUSI is seriously concerned that the UK is still fixated on warmer climes as Russia, america and even China (which is said to be trying to buy a port in Iceland) eye the arctic and North atlantic.  The Russians showing up stirs up a lot of Cold War memories,  he says of the arrival of an entire carrier group in the Moray Firth last week.  But it is more than that. There are significant strategic issues in this part of the world and we have been distracted elsewhere.  During the Cold War, Royal Navy ships and subs, often based in Scotland, picketed the seaways between Greenland and Iceland and Iceland and Britain. Russia plans at least one new nuclear-powered aircraft carrier for the arctic while Willett questions if the UK is even planning to build ships that are capable of thriving in such waters.
