Was it illegal to express sympathy for Nazi Germany during WW2 in Great Britain?
Say you are a citizen and you want your goverment to make peace with Hitler. You even want GB to become a puppet state like France did. Were you allowed to say so in public and start a campaign asking politicans to do this?
Or would this have been illegal, since you are supporting an enemy during war?
I assume it would have been illegal, but I just found fines for breaking the blackout law or not helping in the (war) industry. What would be the punishment? In Nazi Germany it would be called "Wehrkraftszersetzung" (destroying the war ability) and be punishable by death.
