"As German Jews will tell you, the Nazis were not a major group before around 1929. It was a fringe group, like the KKK, which often held small rallies under bridges or in living rooms. In the wake of the War Guilt Clause and global recession, many Germans – agitated, desperate and uninformed – began searching for a saviour and a scapegoat. "
That statement is utterly false and an utterly false narrative. The Nazis and Fascism emerged in a time of radicals. People were not just searching for saviours and scapegoats. WW1 ended in the Russian and German revolutions. In Germany the Weimar Republic emerged as a compromise but there were street battles between pro and anti communist groups on going until the Nazis came to power. Germany was nearly in a civil war. 
The Russian revolution was a humanitarian disaster with millions of killed and dispossessed, deported to gulags and Siberia. 
The Nazis (National Socialists) were created specifically to lure fanatical International Socialists.
