That's when it hit the Western mainstream but the talking points began getting developed in the late seventies samizdat. Interestingly the mainstream Polish dissidents tended to be less Russophobic in that way. That might have something to do with the dueling Polish historical traditions of left nationalism - politically very Russophobic, but culturally Russophile and identifying strongly with the Westernizer tradition and right nationalism - politically Russophile but seeing 'real' Russia as the Slavophile one and thus as something utterly alien from and inferior to 'the West'.
