Looking at history, it's western intervention leading to far right in both though. Ukraine saved itself from Nazism thanks to communism, and only after western-style capitalism took control have far-right movements taken place. As for Iran, I wish Mosaddeq hadn't been ousted by the west too, but alas it's again not "tankie lies" leading to violent regimes, it's western meddling. The tankies you hate have advocated since the past century against the ending of the USSR (which would have saved Ukraine from the demographic and humanitarian disaster it's suffering for the past 25 years) and against intervention against Mosaddeq. If you had listened to the tankies 70 years ago, there would be no far right.
