The illegal dissollution of the USSR was one of Humanity's greatest tragedies, and anyone who thinks the Russian Federation is an improvement needs to do some serious introspection.
What was so illegal? Possibly the millions of USSR citizens taking the first flight or ride out of the Soviet bloc when it became available. Very illegal to the proletariat I'm sure.
The majority of Soviet citizens wished to retain Socialism, a fact that continued after the dissolution. The people fleeing newly established Capitalism was due to dissolved safety nets. 7 million people died due to "Shock Therapy."
Putin is a shithead, but he is popular within Russia. His opposition has not been able to beat him, though the Communist Party has some support as well.
