Strategic bombing in the post–Cold War era is defined by American advances in and the use of smart munitions. The developments in guided munitions meant that the Coalition forces in the First Gulf War were able to use them, although the majority—93%—of bombs dropped in that conflict were still conventional, unguided bombs. More frequently in the Kosovo War, and the initial phases of Operation Iraqi Freedom of 2003, strategic bombing campaigns were notable for the heavy use of precision weaponry by those countries that possessed them. Although bombing campaigns were still strategic in their aims, the widespread area bombing tactics of World War II had mostly disappeared. This led to significantly fewer civilian casualties associated with previous bombing campaigns, though it has not brought about a complete end to civilian deaths or collateral property damage.
