No doubt the most effective counter to this -show of force (really) would be to completley ignore it as has already been suggested-you cannot project power if no one can see or hear it and for all his many sins Putin is not an idiot and probably i about number 50 on a list of world leaders who would start a war (unless of course its in his (as he sees it) back yard.
At my age its easy to look back and see how much money we spent countering a threat that was only there to counter a threat from us and where by and large the equipment for doing so didn't work very well anyway. So, I don't want to see General Dynamics BAe systems etc get rich by re-armament at the expense of the NHS and Pensions unless of course we save so much money from leaving the Eu we will be able to re build the navy-re fund the NHS and built another four High Speed rail links and hub airports as we were promised
