The Gulag Archipelago is the dystopian future after (((Those People))) successfully destroy Western civilisation by flooding it with gay Muslims, of course.

solzhenitsyn is pretty sus too, with all that him being orthodox fundamentalist, fan of tsar, panslavic antisemite, 2000s putin fan (died three days into russian invasion of georgia), proponent of enlargement of russia to include "sufficiently russified" parts of belarus, ukraine and kazakhstan and therefore opponent of ukranian independence; also

Solzhenitsyn made a speaking tour after Francisco Franco's death, and "told liberals not to push too hard for changes because Spain had more freedoms now than the Soviet Union had ever known."

In 1983 he met Margaret Thatcher and told her "the German army could have liberated the Soviet Union from Communism but Hitler was stupid and did not use this weapon"

Regarding Ukraine he wrote “All the talk of a separate Ukrainian people existing since something like the ninth century and possessing its own non-Russian language is recently invented falsehood” and "we all sprang from precious Kiev".

Solzhenitsyn was a supporter of the Vietnam War and referred to the Paris Peace Accords as 'shortsighted' and a 'hasty capitulation'.

Solzhenitsyn was critical of NATO's eastward expansion towards Russia's borders and described the NATO bombing of Yugoslavia as "cruel" [...] Solzhenitsyn accused NATO of trying to bring Russia under its control; he stated that this was visible because of its "ideological support for the 'colour revolutions' and the paradoxical forcing of North Atlantic interests on Central Asia"
