Idea: To slow down US involvement in WW2 after war was already declared, Hitler gets the wild idea to load say ten U-Boats with elite German infantry. These U-Boats are deployed to the east coast of the United States where they unload the German infantry in isolated, unpatrolled areas. Armed with lmgs, smgs, some bombs, and a crap ton of ammo, the Germans split up into small groups, move inland, and begin a war of terror against the United States.
After several days, and thousands of deaths, the German soldiers are caught/killed. In response to this crisis, could Operation Torch be postponed and US soldiers are instead deployed all along the East coast? Would there be enough German hatred in the country to start putting hundreds of thousands of them in internment camps? What other impacts would there have been?
