In reality, neither the US Army nor US Navy was in shape for war in terms of manpower, size, military hardware or experience.

The crews of the Texas and the New York, the two newest and largest battleships, had never fired a gun, and the morale of the sailors was low. The Army and Navy air forces were tiny in size. Despite the flood of new weapons systems unveiled in the war in Europe, the Army was paying scant attention. For example, it was making no studies of trench warfare, poison gas or tanks, and was unfamiliar with the rapid evolution of aerial warfare. The Democrats in Congress tried to cut the military budget in 1915. The Preparedness movement effectively exploited the surge of outrage over the "Lusitania" in May 1915, forcing the Democrats to promise some improvements to the military and naval forces. Wilson, less fearful of the Navy, embraced a long-term building program designed to make the fleet the equal of the British Royal Navy by the mid-1920s, although this would not come to pass until World War II. "Realism" was at work here; the admirals were Mahanians and they therefore wanted a surface fleet of heavy battleships second to none—that is, equal to Great Britain. The facts of submarine warfare (which necessitated destroyers, not battleships) and the possibilities of imminent war with Germany (or with Britain, for that matter), were simply ignored.
