In the Persian Gulf War the U.S. Air Force (USAF) demonstrated that a new era in strategic bombing had begun. Air power could now destroy key portions of a county's military and economic infrastructure without resort to nuclear weapons and heavy bombers and with low losses to both the attacker and enemy civilians. This achievement rested on technology, which both increased bombing accuracy and decreased the effectiveness of enemy defenses, and the reexamination and reapplication of traditional strategic bombing theory by USAF planning officers.
