The title on Qmap is wrong. The flag on the left is the Antifaschistiche Aktion group, which opposed the Nazis. They were commies.
Germany and the USSR had a pact.
Not Nazis and Commies within Germany.
There was incredible hostility between the groups.
Q's point was to show the same forces were affecting events back then as today.
Hegelian dialectic - banker-financed groups instigating and provoking a reaction on the other side for larger, destructive purposes.
