It seems like the US, UK and the EU are very selective when they bang on about 'democracy' and the right to vote'. The government ruling in Kiev now was not elected, but was immediately recognised by the West. It didn't matter that at the heart of those wanting to get rid of the democratically elected president, were a bunch of ultra nationalists and fascists. When all the old symbols, and the flag of the Nazi collaborating Ukrainian Insurgence Army appeared, and are still prominent today, this set alarm bells ringing amongst the Russian population. I think a similar alarm would be set off if the Swastika appeared on the German flag.
Whether the politicians in Westminster like it or not the people of the Crimea have voted to join Russia. British politicians can't have it both ways when they go on about self determination for nations and the sanctity of voting to determine Gibralta's and the Falklands future. Westminster keeps claiming that it is right for the Falkland Islanders and Gibraltarians to determine their future, by a vote, then the same should be fine for those in the Crimea to vote on their future and with which country they want to align with. There is the smell of hypocrisy wafting out of Westminster that implies there is one rule for some and other for others. There again it didn't stop those in Westminster from showing their hypocrisy when the democratically elected Morsi was disposed in Egypt and the army returned.
The one thing that Westminster will not do and that is tamper with the City of London's money making racket, in particular Russian finance. And they certainly won't stop Russians buying property in London, a major reason fueling London property prices. The US are calling for economic sanctions because it does not affect them, it is their way of damaging the City of London. Those at Westminster knows there are high stakes for taking economic actions against Russia and they are not about to bite off their noses to spite their faces.
