Stopped reading there.
The "Stalin-era anthem" was the anthem from 1944 to 1977 and included lines in praise of Lenin and Stalin.
In 1977, Stalin's name was removed, and the rest got a rewrite, concentrating on nation and party.
After the 1990 collapse, a completely new anthem was adopted; it was an instrumental, without (official?) lyrics.
In 2000, the melody written in 1944 was reinstated, but with new lyrics in praise of Russia and naming one individual-- GOD.
Yes, Russia turned so hard that the anthem dropped two atheist Communists and elevated the Deity.
Only the first line of the chorus has survived from the 1944 anthem:
Славься, Отечество наше свободное
(roughly) "Be glorified, our free fatherland".
I have been privately informed that the 1944 anthem was superseded earlier, in 1953, after the Krushchev “Secret Speech” denouncing “excesses under Stalin.
I have not seen the lyrics from that supersession and must take it on faith (my informant being trustworthy) that there was a 1953 version itself superseded in 1977.
yours is an interesting analysis. Have never seen an analysis of the Russian national anthem before.
Also, in my research, it appears that Russia and most Russians are strongly moving away from Marxism, Lenin, Stalin and Soviet Union policy and significantly toward (organized) Christianity, Capitalism, Markets, and a strong Russian Federation.
