Russia and Ukraine are locked in a war that has outlasted any realistic forecast. Why are these nations still engaged in a conflict that is so detrimental to both sides? Because these two countries have a shared history that includes scorched earth and the wilful destruction of personal property rather than forfeiture, the most likely outcome is either complete victory for one party, or regime change that brings the war to a rapid conclusion. Over a thousand years of invasions, occupation, and suffering have influenced the psyches of both the Ukrainians and Russians in ways that make only two outcomes likely.
