Indeed, I believe that Nigel Farage was 100% right on the Ukraine and Crimea. The EU's relentless creep East into the Ukraine, was more than Putin was going to stand for, and the EU's interference in the political regime of the Ukraine, was always going to get a reaction. What we've seen in the Ukraine is a coup against a democratically elected, though corrupt, government this coup backed by the EU that is seeking geo-political advantage.
Remember that Russia and the Ukraine entered into a treaty which allowed Russia to station up to 25,000 troops in the Crimea and the Ukraine was handsomely rewarded for that. Also, the Russians have a long standing naval base in the Crimea for their Black Sea Fleet. The re-annexation of the Crimea by Russia (it was only transferred to the Ukraine in the 1964) has been grossly mis-reported in the Western mainstream media that plays to the EU tune.
Anyway, if we leave the EU then the rest of Europe - and the Ukraine as a potential new EU monster member state - can continue with their untreated obssession with making a reality of George Orwell's 1984 and becoming the playthings of bureaucrats and technocrats. Personally, I don't want to be standardized, homogenized and harmonized under an EU 4th Reich jackboot.
