It seems that by the year 1980, the United States had managed to recover from the Nazi occupation as the reestablishment of the FBI and a certain industrial capacity to make and improve weapons, as well as the United States Armed Forces that is training troops. the United States has been restored to democracy and removed fascism from power, becoming a Federal presidential constitutional republic once again, and most or all vestiges of Nazi censorship and control have been removed or nullified. A thriving film industry is once again based out of the United States, producing VHS/UVK productions such as the anti-Nazi action film Pink Mist that occasionally gets smuggled into Nazi Germany and occupied Europe.
