At the beginning of WWII, American public opinion was against joining the war or even supporting European Allies. In 1940, Henry Ford refused a U.S. government contract to build Rolls Royce aircraft engines for England. Other automotive manufacturers didn’t want to turn making cars over to war production either. It took the attack on Pearl Harbor in December 1941 to change American minds and convince U.S. industry to become patriotic. Read more about WWII in A Brain. A Heart. The Nerve. (see NOVELS).
