Well, Newport is already in nigh-on lockdown: Putin was careless in bringing this to a head so shortly before a NATO Ministerial, as his policy has now moved from head item on the agenda, to become objective no 1 of the construction of an emergency intervention force. The game of weasel words has ended: he pulled the tail of the tiger once to often and the claws are coming out. The debate as to whether this is a good thing or a bad thing is not my concern, I simply describe the facts: Putin's bluster about not messing with a nuclear power worked both ways, and it took us straight back to 1974, with the exception that Russia no longer has the buffer states to drain financially.
Of course, Putin's not the man who's paying the bill, but his oligarchs, which may have consequences for him.
There may be no end of bluster from all sides, but unless you are at the table it's just so much hot air. I at least have worked with those doing the planning and they are not warmongers: but sometimes nipping a small problem in the bud preemptss a larger one, the least worst option.
