The reality is that totalitarian armies kill everyone until way past time their enemy has surrendered.
In reading WW2 history the Allies were executing German civilians who were still fighting against the Allies, one as young as fifteen. So if America was defeated in a war on our soil would you still fight against the invaders even if our government capitulated? This is a rhetorical question.
What was the difference between the USA and it’s WWII enemies? EASY!!
The difference is a nations actions in VICTORY.
When and where victorious, the Germans and the Japanses got down to the REAL business of mass killing. In the areas where hey were victorious, the atrocities were legion.
When and when the forces of the United States stood proudly in VICTORY——THE KILLING CAME TO AN END!!!
Then we disarmed and went home.
