The Russian forces that fenced Aleppo were headed by Kadyrov, who led Putin’s genocidal operation against the Chechen people
Putin's regime is characterized revival of some medieval traditions in Russia....the drunkenness, rudeness, domestic violence, clericalism. The reasons are many. "Our" Russian reactionary ("redneck") is convinced that justice in the world no to achieve; that "the rights of one who is stronger." Therefore, he justifies the dirty war against the people of Syria, supports regimes, as the Assad's regime, only because it is beneficial to Russian imperialism.
And also, in such a reactionary logic is absent: the relation of cause and effect. Putinists can applaud at bombing Syria. But at the same time be in a rage on how Syrian rebels kill war criminal-pilot.
By the way, a classic example of a medieval order - is the unlimited power of Putin's protege Kadyrov in Chechnya. Bandits of Kadyrov are responsible for the beating and killings of many women, rape and so on. "Army" Kadyrov putin's regime recently sent to the occupied eastern Aleppo as "Russian Military Police".
