In reply to Shein.

He didn’t really do it single-handedly though he deserves most of the blame. He wasn’t the founder of the Nazi party, he came to lead it to victory and became its most prominent member. In other words there were plenty of people willing to flock to his message of scapegoating Communists and Jews and blaming them for the outcome of WWI. He wasn’t a particularly brilliant person, just good at exploiting people’s hatred and racism.
