During the 3-1/2 years of World War II that started with the Japanese bombing of Pearl Harbor in December of 1941 and ended with the surrender of Germany and Japan in 1945, "We the People of the U.S.A." produced the following:
22 aircraft carriers
420 destroyer escorts
34 million tons of merchant ships
100,000 fighter aircraft
24,000 transport aircraft
58,000 training aircraft
257,000 artillery pieces
3,000,000 machine guns and,
2,500,000 military trucks
America 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, developed the atomic bomb and, ultimately, conquered Japan and Germany.
It's worth noting that during the almost exact amount of time, the Obama Administration couldn't even build a web site that worked or devise and execute a plan to protect Americans from terrorism!!!
