The Orange Revolution was a failure in no small measure than because of the 2004 constitutional changes which created political gridlock and government dysfunction. Those changes and the way they were enacted were criticized at the time, both within Ukraine and by the West. Yulia Tymoshenko was an outspoken critic of the 2004 Constitution prior to her election at President.
Ukraine needs a new Constitutional order, but is unlikely to get one anytime soon. The February 21st agreement negotiated by the old goverment, the opposition leaders, Russia, and Europe was the road map to Ukraine's future, but that document was tossed aside by the puppet fascists before the ink on their signatures was dry.
Thank you for your expert opinion. My faith in your vast knowledge about Ukraine is only slightly diminished by the fact that you incorrectly believe Yulia Tymoshenko has ever been the president of Ukraine. Also by your constant lying and pushing of Russian propaganda.
