You're saying that the US embassy in Moscow doesn't know how Russian politicians and military figures think, and is full of useful idiots.

Another theory is that the US embassy has constant contact with Russian political and military figures, is very familiar with how they think, and accurately reported their views back to DC in order to help the US government formulate its foreign policy.

Ironically, I think you're the one who has swallowed a narrative hook, line and sinker.
