FILE – In this file photo taken on Monday, Aug. 19, 1991, Boris Yeltsin, with papers in hand, president of the Russian Federation, makes a speech from atop a tank in front of the Russian parliament building in Moscow, U.S.S.R. No picture better tells the story of Russia’s failed 1991 coup than that of a fist-pumping Boris Yeltsin defying Communist hard-liners from the top of a tank. Those who were by Yeltsin’s side describe his decision 20 years ago Friday to climb onto the tank as a stroke of political brilliance that proved crucial for the defeat of the coup. (AP Photo, file)
