They didn't just not present an obstacle, it's far worse than that. The "leftist" orgs were at the vanguard of the repressions and denunciations. They were among the most enthusiastic supporters of the anti-Russian witch hunt. They were so desperate to prove that they were not with "the enemy" that they became "more catholic than the pope" as the saying goes.
I don't know exactly what it was in Europe that caused this derangement. At least the US left has the excuse of having their brains broken by the Russiagate psyop. But the European left has no excuse. I guess Europeans are just deeply russophobic and really enjoy thinking of themselves as culturally superior and more civilized than "those eastern barbarians".
Well there is the factor of "looking towards" the West instead of the East. For some reason or another, some backward countries see the West as progressive and the East as conservative, this is a misconception deeply rooted in some societies. But why leftists would actually adhere to it, if only to appease to a wider electoral body, is a mystery to me. Leftists aren't usually the ones to blindly follow liberal propaganda.
I don't think it's that much of a mystery, they're simply racist/chauvinist.
