The US military is really good at destroying things, not so good at actually winning wars. From Patrick Armstrong at strategic-culture.org:
“If you want a single word to summarize American war-making in this last decade and a half, I would suggest rubble.”
The American Way of War is founded on three assumptions. Ever since 1945 the USA has assumed that it would have air superiority: it knew that it would have to fight for it against the Soviets but assumed that it would be able to gain it, at least in the areas where needed (local air superiority). In Korea there was some resistance but the USAF was able to bomb pretty freely. Wikipedia informs us that it dropped more bombs on Korea than it did in the entire Pacific Theatre and about half as many as it did in the European Theatre in 1941-1945. North Korea was obliterated: “We went over there and fought the war and eventually burned down every town in North Korea anyway, some way or another, and some in South Korea, too.” Which, of course, is the principal reason why North Korea has nuclear weapons today.
Bombing became the American Way of War par excellence with ever greater tonnages dropped: Cambodia received about the same amount as Korea, Laos about three times as much, Vietnam about six times as much. And the bombing continues today throughout Washington’s forever wars. Officially it is precise, surgical, carefully selected: “The targets I’m assigned to destroy have been vetted through the most professional members of our armed services, and (I know) that others are taking their jobs as seriously as I am“. But U.S. Precision Bombing is a “Persistent Myth” and the reality is quite different:
Since World War II, the U.S. Air Force has loosened its definition of “accuracy” from 25 feet to 10 meters (39 feet), but that is still less than the blast radius of even its smallest 500 lb. bombs. [Here’s one.] So the impression that these weapons can be used to surgically “zap” a single house or small building in an urban area without inflicting casualties and deaths throughout the surrounding area is certainly contrived.
