Hitler’s surviving U.S. relatives by his half-sister swore a blood oath to each other to never have children of their own and thus make the demon gene die out.
But suppose a child was born in these times who was genetically identical to Hitler?
His rise to power was a combination of gigantic events prior to which Adolf Hitler was an abject failure. The World War, hyperinflation, social unrest & many other factors were what gave Hitler his opportunity.
A latter day Hitler would be as laughable as Mr. Hilter & Ron Vibbentrop & Heinrich Bimmler in the Monty Python sketch, complete with the Victrola on his bicycle playing Deutschland uber Alles.
