Again, the NYT is openly stating (finally) it was a US backed coup d etat and you are now melting down about it.
In addition, you are completely leaving out the massive trade implications for the Ukraine vis-a-vis one of its largest trading partners if it entered into the EU agreement, and the fact that many Ukrainians were not at all pleased with the demands the EU was placing on the Ukrainian government.
But alas, that is not even remotely close to being a justification for Vicky Nuland and the #neocons in formulating and executing a coup in Ukraine.
