Same time, it's somewhat half serious.
After WWII the allies were much more punitive and unforgiving towards the Nazis than Fascist Japan imho.
General Dwight Eisenhower, himself a German-American, spearheaded the campaign to eradicate Naziism from a Modern Germany. In fact, Eisenhower despised his Nazi German enemies & showed little mercy towards German POWs. He was harder on his own kind than anyone else. It's widely thought that he ordered German officers shot or let them starve to death. Many German officers endured severe hardship as they were sent to concentration camps in the USSR & not allowed to return to Germany as late as the 1950s.
So while they banned Nazi symbols such as the Swastika in Germany, they are present elsewhere such as the Bhuddist religion in places like Japan, Asia and India.
