Grain embargo on USSR, don't recall anyone starving.
Per Iran, I don't care if they don't wan to sell THEIR oil, but that isn't what they have in mind.
The truth is that Iran would quickly be reduced to economic ruin if we blockaded their ocean going imports and exports.
Yes they have land borders, but its tough to truck that much oil, and their neighbors will be taking a sizable cut for the access.
The question was whether we had used grain as a political tool.
Their harvest had fallen 21 percent from the previous year. The embargo would have had more effect, but the USSR just found other suppliers in Europe and S. Africa.
Central control and distribution meant people were always starving and suffering from shortages of all kinds under the Soviets.
