German operational success struck a society whose military and political leadership had been deeply marked by the Western Front. The collapse is interpreted as psychological and political as well as military, with shock magnified by memories of extraordinary First World War losses. The counterfactual therefore requires more than a different battlefield maneuver: France must decide to endure another destructive campaign on its own territory. If that political decision holds, French historical persistence makes a quick surrender far less likely even though the military position remains severe.
