This chap was warning us 40 years ago of how then the USSR and no doubt now Russia influences western , politics , media etcEarly on in the war, I watched a video by an academic, whose name escapes me. The gist was that Russia has been at war with the west for decades. It is just that the west hadn't noticed, at least until the invasion.
It may be years, or decades, or never, until we find out the true scale of Russian interference in western politics, elections, referenda etc.
