Looking it up, it seems that one of the sources (_the_ source?) cited, "Executive Intelligence Review" was published by Lydon Larouche. The infamous former-Trotskyist-turned-strange-conspiracy-theorist-and-cult-leader. I might be misremembering the specifics, but his followers always seemed a bit bonkers to me (believing in a secret 'war' between the Vatican and the British royal family, the latter in league with 'the Jews'). The David Icke of his day. So that doesn't strike me as a particularly credible source.
All the same, it's fascinating what a long overhang the USSR has - what started as an ideologically-motivated scheme to change the world then morphed into a means of furthering the power and paranoid self-interests of Stalin as an individual - with a trace of residue ideology and a lot of added Russian nationalism mixed in - and now seems to have continued, under Putin, long after the collapse of the country and regime and even belief-system that spawned it, to the point that these sorts of stories about Trump can appear at least vaguely plausible.
