As another round of talks start up to try to negotiate an end to the war sparked by Putin's invasion of Ukraine, President Zelensky of Ukraine has continued to warn about the risks inherent in trying to buy Putin off by offering him pieces of another country's territory. It is "a big mistake to allow the aggressor to take something," he reportedly put it.
I was reminded of something I was just reading in Montesquieu's Considerations on the Causes of the Greatness of the Romans and Their Decline. He says that the Western Roman Empire, in its waning days, sometimes made overtures "to appease with money the peoples threatening invasion."
