Bruno had been given the greatest honor by the Kaiser, and that was operational command of the entire Western Front, the only major front left that Germany really cared about. As a result, he was no longer given the option to command in the field, and the German 8th Army he had been in command of now fell to the control of Heinrich who by no was a Lieutenant general.
As a result, Bruno would be spending the majority of what remained of the war far enough away from enemy lines to be threatened by the enemy, but close enough to maintain full control over every front and the forces of the Central Powers located there.
Because he was no longer stationed at the chaos of the front, Bruno had easy access to ongoing news around the globe. Hence he immediately heard about what happened in French Indo-China and the field day the United States Press, who was not under his control, were having with it.
