I think that Putin also knows that the UK has very little that would be a threat to him.
In fact most of Europe is in the same boat......and I don't think that the US has the stomach for such a conflict.

Putin is a little man who wants to appear big.
As for him not turning off the gas......he would do it in a heartbeat. How long do you think it would be before the countries who rely on Gazprom to capitulate?
My guess is not very long. So he would have no fear of losing money.
