I'm not an American so not educated on this. Are the sanctions considered successful? What are their goals?
The goal was Cuba was openly hostile to the US and so we swung our large economic …stick, around. They took our assets and then held nuclear missiles for the Soviet Union during the Cold War, essentially putting them incredibly close to our shores.
They’re lucky the US didn’t do more, frankly.
I think those missiles were installed (at least partly) as a response to US deploying nuclear weapons in Turkey (and, to a lesser extent, Italy).
