Strategic bombing
Strategic bombing is a military strategy used in a total war with the goal of defeating an enemy nation-state by destroying its economic ability to wage war rather than destroying its land or naval forces. It is a systematically organized and executed attack from the air which can utilize strategic bombers, cruise missiles, or nuclear-armed fighter-bomber aircraft to attack targets deemed vital to an enemy's war-making capacity.
