IRL, StB were ok, some solid FI ops, but they were no Stasi (or UDBA). Many hot StB ops got handed to KGB overlords.
KGB surely had operational files on Trump after his 1987 USSR visit. We have no idea what they said, and StB files shed no light either: they would have given KGB whatever it wanted.
