Yes and no.
The CIA has and probably still til this day has ties to drug trafficking organizations.....Often times for the sake of the "big game" (helping keep some regime happy/fund them)....But not every major supplier is sanctioned.
Ports are too big, organizations too intricate and crafty, geopolitical situations become too unstable to devote full time and attention to...Alot of govt legwork is fully reactionary, only addressing a problem when they have a moment too, which can take decades.
Ports too big. LOL.
US doesn't have to control the ports, they are in the countries where the shyt is grown and manufactured.
You think the US doesn't know who the organizations and bosses are that operate in their field. LOL
Geopolitical situations that are unstable most likely because of the US government's shadow operations.
US domestic talk about drugs isn't adressing anything its blowback and PR cover, they are going to do what they do because its how they have always operated and how they fund itself off the books (CIA).
CIA manufactured a war with Afghanistan, with no proof and no afghans involved, because the Taliban had finally started the offensive to take out northern alliance drug dealers and were about to take full control of the country.
US takes over and continues a war in Vietnam and launch a civil war to keep drug production following. This is the level of international meddling and range the US operates in to keep the drug game going. This was going on pre-WW2 and picked up during and after WW2 with the FBNN's connection with Italian and Jewish gangsters to ship drugs and transport them internationally.
Its bigger and more embedded than you imagine
