I can remember when I was National Security Adviser, the intelligence community told us... they put out an intelligence report saying that Iran would never back off from attacks on shipping in the Gulf if we use force.
My understanding is that what was provided was general order of battle information, not operational intelligence. I certainly have no knowledge of US participation in preparing battle and strike packages and doubt strongly that that occurred.
Intelligence is not a science.
Policymakers have to make judgments based on the best intelligence they get.
