... Frankly, all Presidents should be wary of our own CIA. If Obama was still president, you would be telling us how bad the American CIA is. But since Trump is president, anything that opposes Trump is good in your book even if bad...
Just look how virulently anti-Trump the former CIA director is. People like that (and like Comey in the FBI) are still there.
The role of CIA is not to formulate foreign policy, but to provide information to those who are elected to do so. Those providing the information are trying to insert their own slant to it.
I worked in the American embassy in Belgrade for seven years. I saw first-hand how information is gathered and interpreted at the grass-root stage, based on a particular embassy officer's worldview or his/her idea of which view is in vogue in Washington and what is going to get them promoted. I did not have access to the classified information, i.e., the final version of the report, but, as I said, I had a pretty good insight in the origins.
In other words, info coming from embassies, intelligence agencies, etc. should not be treated as the gospel, but just as one of the facets necessary for those elected to formulate foreign policy.
