The history of Palantir:

Christine Maxwell and Alan Wade found Chiliad, a database surveillance application that was used in the FBI. Then Alan Wade became CIO at the CIA. Then In-Q-Tel (CIA) co-founded Palantir with Thiel.

Karp, who was at Haverford college with Epstein's neighbor Lutnick, became the philosophical ideologue for Palantir.

With these overt and easily verifiable connections it is beyond belief that any European state would even consider using Palantir. The governments do not even work any better with all that surveillance software, they work worse than 20 years ago. So even the "we need it" argument is a fallacy.
