I truly appreciate your honest attempt at civilized discussion on this topic. But, CIA edited Wikipedia, is not where honesty is to be found. Remember Pompeo's admission, "We lied, we stole, we cheated." To that point, It is completely disingenuous and downright deceitful to imply that Russia "annexed" Crimea. They did no such thing. Western polling companies, Gallup and Pew Research document that Crimeans, pre and post Maidan, were overwhelmingly Russian. They were Russian for all but 40 of the past 300 or so years until Krushchev decided, in a drunken stupor, to give back Crimea in 1954. Crimea voted for self-determination and protection from the rabidly anti-Russian, neo-Nazi Stepan Bandera types responsible for the violence on Maidan. 97% voted in favor of rejoining Russia after witnessing the ethnic cleansing in Donbass, Lughansk and Donetsk that voted over 90% in favor of Yanukovych. Tens of millions of Ukrainians and Russians living in Eastern Uk are inter-married and work in Russia.
The reason Yeltsin is as of today, the 3rd most hated man in Russian history is because he A) sold off state's assets to western oligarchs for pennies on the dollar while enriching himself and B) did not a damn thing as NATO marched right up to Russia's borders, encircling them. Russia's most loyal ally, Serbia was bombed for 78 straight days and Yeltsin sat on his hand while the other hand was out collecting cash in brown bags. 13 former Warsaw Pact members were swallowed up by NATO in violation of the 1991 agreement by James Baker on behalf of GHWB, not to move 1 inch to the east if Gorbachev would allow the re-unification of Germany. Shortly thereafter, Clinton was annexing Kosovo. It is crystal clear who is the aggressor. It was spelled out by Halford Mackinder in 1904 before the Royal Geographical Society in London. He who controls the Heartland (central Eurasia) Ukraine-Russia, controls the Asia pivot to China and India. It's where the world's greatest population sits and Russia has $75 TRILLION in natural resources. Our oligarchs want it for themselves. Not for America. Zbigniew Brzezinski (Obama's main foreign policy advisor) was a practitioner of Mackinder. He wrote about this in his book, The Grand Chessboard.
Nor is it honest to say that Russia invaded Ukraine. Russia was already in SE Ukraine under the Kharkiv Accord. It was due to expire in 2017. However, an extension was agreed upon by Yanukovych and Medvedev in 2010, thus tacking on another 25 years onto '17 with a new expiration date of 2042. Russia will NEVER give up their warm water ports in the Sea of Azov-Black Sea. It's absolutely critical to their survival. Witness Napolean and Hitler invading. Nor is the Kremlin willing to take on more pensioners in Ukraine that Putin is struggling to pay for now after their government collapsed twice in the past 100 years.
Washington overthrew a democratically elected government in Kiev and installed their puppet, Yatsenyuk, just as promised by Victoria Nuland (Dick Cheney appointee) only 18 days before the violent coup on Maidan. Nuland also bragged in front of Chevron banners that the USA spent $5 Billion to accomplish this goal. George Soros admitted his role in events achieving this coup to Fareed Zakaria. His TV station, Hromadske, started in November 22nd 2013 and started fomenting violence on Maidan just after Yanukovyck rebuffed Merkel, Obama and the west at Vilnius. He was supposed to sign a European Association Agreement and eventually join NATO. He wanted a tri-party agreement as much business was already done with Russia. George Friedman of the CIA's Stratfor, called it the most blatant coup in history.
So, in closing, the Budapest Memo does not hold up.
