I don't want to speculate, because I don't have any specific data on that. I will say this: I think it's well known that Europe turned primarily to Russian energy for what appeared to be a stable alternative to Middle Eastern energy, especially from the 1990s onwards.
A lot of that, I think, was not so much to do with Russian propaganda, although certainly I can see how that would play a role in ensuring that public sentiment in areas that have traditionally been more cordial towards Russia, as well as parts of old Europe, remained opposed to weaning Europe off of Russian energy.
