You need to read the detailed, top-of-the-fold story in today's NYT, based on a year-long extensive investigation:
Russia has attributed Mr. Yanukovychs ouster to what it portrays as a violent, neo-fascist coup supported and even choreographed by the West and dressed up as a popular uprising. The Kremlin has cited this assertion, along with historical ties, as the main justification for its annexation of Crimea in March and its subsequent support for an armed revolt by pro-Russian separatists in Ukraines industrial heartland in the east.
Few outside the Russian propaganda bubble ever seriously entertained the Kremlins line. But almost a year after the fall of Mr. Yanukovychs government, questions remain about how and why it collapsed so quickly and completely.
An investigation by The New York Times into the final hours of Mr. Yanukovychs rule based on interviews with prominent players, including former commanders of the Berkut riot police and other security units, telephone records and other documents shows that the president was not so much overthrown as cast adrift by his own allies, and that Western officials were just as surprised by the meltdown as anyone else.
