Bruno had more or less suspected that France would begin its propaganda efforts. War was more than looking like a certainty for the world as a whole as the years passed. And Germany had begun preparing long before anyone else.
While other nations were still focused on meeting recruitment quotas, Germany was in the process of developing advanced weapons. The latest of which were expected to see full scale production by 1912. Two years before the war would break out if all went according to planned.
Then again, Bruno had caused so many significant changes in this timeline that it was actually impossible to know when the War would break out, and what would be the cause. He often had thought to himself of a dreadful fate of irony, that his assassination by the Black Hand would spark the War without him, rather than the untimely death of Franz Ferdinand.
