For one thing, we know the CIA declined a help offering for the Bay of Pigs assault from President Anastasio Somoza's Nicaragua.
It's a pretty sure thing the answer to that is in the secreted CIA documents.
The Jimmy Carter administration subsequently betrayed Nicaragua and sold them out to the Cuba-sponsored Communist Sandinista terrorists. Why? To advance his agenda of building a Marxist hemisphere which is advanced by the US NED, another foreign meddling US congressionally funded tax shelter.
Even still, the former US president, Jimmy Carter's taxpayer-subsidized Carter Center interferes in the affairs of foreign nations. We suspect, but yet have no evidence that his "charitable center" is an intelligence conduit for the CIA .
Somoza was a solid American patriot and 1946 graduate of West Point. The real story of throwing a US ally under a bus can be read here, Nicaragua Betrayed. Highly recommend.
