In 1980, after the Soviet invasion of Afghanistan, President Jimmy Carter came up with a way to retaliate: stopping grain sales to Moscow. The boycott, said Commerce Secretary Philip Klutznick, would prove to the world that “aggression is costly” and induce the Soviets to “halt their aggression.”
The Soviets did halt their aggression and pull out of Afghanistan. But that didn’t happen until nine years later, and it had nothing to do with the grain embargo. American farmers suffered because their prices dropped, but the Kremlin managed to buy grain elsewhere. So the following year, President Ronald Reagan lifted the ban.
The fact that those sanctions proved useless has not stopped President Barack Obama or congressional Republicans from proposing new ones. On Thursday, the president announced he would deny visas and possibly freeze the assets of Russian officials and entities deemed complicit in the invasion of Ukraine.
