I wonder if Europeans have any clue that this company is a CIA enterprise/front?

Their own countries' representatives, and certainly their intelligence services, are also CIA enterprises/fronts. And the CIA (and the US diplomatic corps as a whole) are just representatives of elites, and their sole purpose is to protect those elites' business interests. At the dawn of the project they only employed elite children and ex-Nazis.

That's the other major flaw in the "decouple from the US with European alternatives" marketing campaign. These "US" companies don't have any more loyalty to the US than they have to your country. Their investors are from all over the world. Their employees and executives are from all over the world. If your "European alternatives" to a technology-enabled total surveillance state are owned by the same people, isn't the entire conversation silly? Are you arguing over whether the PO Box is in Delaware or in Germany?

NATO is more obedient to US intelligence than Palantir. Palantir gives orders to US intelligence. The purpose of NATO is to indulge the unearned sense of superiority of EU/British citizens and their denial that the reason they were partially occupied by Russia is because they launched a war of extermination on Russia that killed 20 million civillians. It indulges it in order to manipulate guilty Europeans to do what Palantir wants.

The paranoia that has been whipped up in the European middle-class about Russia is similar in nature to the paranoia that gets whipped up in the US about black Americans. White Americans imagine that black people are going to rise up and kill them all because they can't help but imagine how they would feel about being enslaved and having the children of those enslavers walking around with the fruits of that, calling them lazy. Non-Jewish Europeans imagine how they would feel if the Soviet Union had invaded Europe, walked into tens or hundreds of villages, rounded up all the citizens and put them into a barn, then set the barn on fire. "The USSR must want to kill us all," they think.

It's only natural that they call the Americans to save them. We literally preserved Spain (the initial event of the war) for the fascists, and West Germany for the Nazis that we didn't feel were valuable enough to import to the US itself.

They don't care
