Soviets still planned WW3 ,MAD or not MAD.Only reason that they do not started that? Reagan showed him,that he knew where their secrets bunkers are,so they would die,too - not only their slaves.
Becouse,from the times of russian tsars,all people in Russia/soviet except tsar are slaves.
So,MAD would not stop new KGB tsar,if he belive that USA do not knew where his bunker is.All to save the world,he would be happy to rule over ashes.
There were free russians/farmers and elites/ but Lenin&Stalin genocided them all.
P.S
@Navarro is right - Dugin is worshipping Stalin,who averagely genocided more people in one week of his rule then combined spanish and papak Inquisitions during 600 years of their existency.
