For the 1300th times: the New York Times concludes that it is all over for the Asad regime

" Russia announced Monday that it was sending two airplanes from its emergency services fleet to Beirut, Lebanon, to evacuate around 100 Russian citizens leaving Syria, reflecting Moscow’s assessment that President Bashar al-Assad’s forces are losing control of the country after nearly two years of fighting."  Wait.  Call me dumb but how did A leads to B?  How did you conclude that the withdrawal of the citizens is based on an assessment that Asad is losing control?  Why not based on an assessment that the place is too danerous and that the civil war will be protracted?
