America's Cuba policy is a failure and continues to be a failure. Do you not think if America opened up to Cuba that wouldn't over time drastically lesson their dependency on Russia?

Cuba really doesn't have much of a choice, they have to trade with "friendly" nations of which America refuses to be.

Fun fact, when we (Canadians) go to Cuba they typically won't stamp our passports because they know it causes us issues when trying to enter the US.
