UK too, and probably every country with some military budget money to waste on psychic boondoggles. Still better than doping your own civilians with LSD for a lark.Remember, even the US and USSR were trying to weaponize psychic powers during the cold war, pouring millions of dollars into remote sensing and other projects.
Dune was written in 1965 and Starship Troopers in 1959, during the period where psionics in literary scifi was still largely seen as quite plausible. The others are all movie and film franchises first and foremost, and the number of really hard scifi movies or shows ever made is arguably in the double digits even if you extend it to "plausible science at the time" like Disney's educational pieces. In literary circles these days, psionics removes a work from the "hard scifi" category pretty much automatically, which wasn't the case in the 1970s.And despite that implausibility, psychic powers, psionics, and telepathy have remained a fairly staple part of the science-fiction genre: e.g., Babylon 5, Firefly, Stargate, Starship Troopers, Star Wars, Dune, etc.
Which is ironic, because there's still a lot of things that are accepted as "hard" or "hard-ish" that probably shouldn't be. Psionics having become a "cheat" while (say) manned missions to other star systems using realistic physics and plausible engineering projections are still a-okay is seriously bemusing to me - and funny. Lot of supposed "hard scifi" writers need to admit they're doing soft science or outright space opera fantasy IMO.
