From this as well as other sources:
During the 3-1/2 years of World War 2 that started with the Japanese bombing of Pearl Harbor in December 1941 and ended with the surrender of Germany and Japan in 1945, the United States produced 22 aircraft carriers, 8 battleships, 48 cruisers, 349 destroyers, 420 destroyer escorts, 203 submarines, 34 million tons of merchant ships, 100,000 fighter aircraft, 98,000 bombers, 24,000 transport aircraft, 58,000 training aircraft, 93,000 tanks, 257,000 artillery pieces, 105,000 mortars, 3,000,000 machine guns, and 2,500,000 military trucks.
About 2,300,000 combat sorties were flown.
We put 16.1 million men in uniform in the various armed services, invaded Africa, invaded Sicily and Italy, won the battle for the Atlantic, planned and executed D-Day, marched across the Pacific and Europe.
In addition the US designed, tested and deployed the two atomic bombs, in the process constructing Los Alamos research laboratory, developed the know how and research to refine uranium and create plutonium weapons, and ultimately conquered Japan and Germany.
During the almost exact same amount of time the Obama administration has been unable to build a functioning web site that can accurately register and track seven million insurance registrations.
