We seem to be spending a lot of time and effort banning lots of Russian bureaucrats fromtravelling to the EU and the US and making orders to freeze assets that they don't hold here and over which we have no control.
The Russians, on the other hand, have stopped reciprocating because they can see that the whole exercise is more trouble than it is worth.
Which is a shame, and a danger to the West, because it allows the Russians to bear a grudge. It is a boil that needs to be lanced, by a pointless act of vindictive retribution. Hopefully one that can set the Russians in a good light and show them as a nation that we can work with.
I suggest a Russian ban on travel by Tony Blair and Gordon Brown, and a freezing of their assets. I might even start a campaign on Facebook.
