he U.S. Army’s reputation for effectiveness during World War T II has not fared well over time, particularly regarding the European theater of operations. This is surprising given what the Army accomplished. Just to refresh the reader’s memory, the United States went to war with a small, impoverished Army that conducted maneuvers with wooden weapons and borrowed vehicles in the years leading up to World War II. Yet within 12 months of Germany declaring war on the United States, the Army invaded North Africa and knocked Vichy French forces out of the war. In another 12 months, it knocked Italy out of the war. And 12 months later, the Army was on the border of Germany, having just defeated Adolf Hitler’s last-gasp effort to stop the Allied onslaught. Nevertheless, these achievements seem to have diminished over time. By way of illustration, ask any military of- ficer which of the following factors best explains U.S. victories in the European theater during World War II: • Army leaders executed an organi- zational miracle in quickly creating Left to right, Henry H.

Fifty years ago, most readers would have chosen the first statement; today, World War II few would.
