The national security rationale for sanctions on Cuba has long since disappeared. The embargo was originally imposed in 1960 when Castro seized US property in Cuba and was tightened in 1962 in response to Cuban alignment to the Soviet Union. These sanctions were in order to neutralize Cuba as a potential threat through it being a proxy of the Soviet Union. Since the Soviet Union has collapsed this is no longer a problem. Instead Cuba is left with no powerful friends and by itself its military power is negligible and is certainly in no position to threaten the world’s preeminent power.
