I would put bets on the issue probably being that it was pointed out that Anthropic's models were used to assist the raid in Venezuela, Anthropic then aggressively doubled down on their rules/principles and the DOD didn't like being called out on that so they lashed out, hard.

If theres anything this admin doesn't like, its being postured against or called out by literally anyone, especially in public.

I don't even think Anthropic balked at being used to assist, as long as a human has the final say.
