Is Britain big enough and strong enough to take on Russia in the ongoing diplomatic wrangles?

Britain had its own sins too. All this diplomatic tit-for-tat with Russia can be traced from events that goes far back years ago. Remember that in the past Britain also rejected Russia's extradition requests of the Russian crooks and oligarchs wanted by the Kremlin and now taking refuge in Britain. Now, the tables had turned and it's Britain's turn to have their requests rejected.
