I would be very surprised if a future democrat government dismantled information sources built on palantir contracts.

They might change aspects of oversight. They might diversify to avoid contract capture.

Sorry to be blunt, but government tends to be amoral when it comes to public noise about things, and actual choices made. Agencies of all kinds from LEA out to health will ask for retained access to the joins over disparate data.

The same across the UK, Europe and the OECD. Plantir is going to do very well, into the future. Some politics will force change. The EU will eventually get robust, onshore, self controlled data analytics and management.
