Civilian casualties of strategic bombing

Strategic bombing is the use of airpower to destroy industrial and economic infrastructure—such as factories, oil refineries, railroads, or power stations—rather than just directly targeting military bases, supply depots, or enemy combatants. Strategic bombing may also include the intent to dehouse, demoralize, or inflict civilian casualties, and thus hinders them from supporting the enemy's war effort.
