Nothing particularly "left wing" about a country with a top tax rate of 13%.
Russia is really as close as it gets to a fascist state these days. It's ruled by gangsters who see the revolution in Ukraine as a threat to their ill-gotten gains, nothing more nothing less. Diplomacy will not work with these people and it is difficult to see what will, other than the sort of economic warfare which I'm afraid the west has no stomach for. Ironically it's the traditional powers of W Europe: German, Britain and France, who are looking particularly behind the pace when it comes to reacting to this. Mind you, we don't know what is said behind the scenes. Hague will know full well the true nature of the Russian beast, but has to stick to diplomatic language.
