You left out Option three outside partys.
Despite how it may seem; It has happened before. A non governmental affiliated group attempts to engage in covert action on their own initiative. Example James Gordon “Bo” Gritz former US Army officer (Vietnam), Special Forces (another Green Beret), “Survivalist”, mediator at Ruby Ridge, Author, Conspiracy Theorist and several times would be third party (Populist) Presidental candidate inspiration for Murdock on the A-Team.
In the 1980s Gritz attempted rescue of Vietnam POWs on his own with a private band of his own. This comes close to your
@Jura #1 but Gritz was turned down again and again. He did it of his own choice not set up by the CIA and failed to find anything.
Option Four, other national intelligence agencies.
The CIA isn’t the only game in town, in this case the Columbian NID. A lot of defectors from the Venezuelan military ran to Columbia and Set up camps as well as their own armies to try and take out the Bolivars. Columbia and Venezuelan relations are not exactly buddy buddy. Venezuela backed FARC and Columbia backs these groups.
