The only society capable of putting man on the moon is the U.S. and they did that 5 years after the embargo was enacted.    Kind of like the 50 year old plus cars which Cubans have been forced to drive and fix with all sorts of homemade parts - again because importing new cars into Cuba is extremely difficult.     Oh, and there are factories to make things like sanitary products but they're not very efficient and use very old equipment - yeah, the embargo includes manufacturing equipment too.
