well "akshully" :-) That agreement was mainly about nukes and NOT joining NATO. Non aggression pact was also reaffirmed in 1997 by Treaty of Friendship but after Yanukovich was gone and power vacuum "invited" Russian to take the advantage (2014 invasion of Crimea) Bottom line is you are right, there is enough blame to go around on both sides. We all know that after Soviet Union collapsed, new Russia would not be happy with its outcome no matter how they call themselves. The beef was going around for decades and hard to pin point one thing that caused the recent conflict. It's wrong regardless... Can we just all get along...??? :-)
