Do any of us really know what our actions will cause? I had an executive at our company make an off hand comment to me. He simply said why don’t you see what’s going on in a particular region. It was an area that we really hadn’t paid attention to. During a slow week where I did not have any commitments, I drove to the region met some people and eventually scored several massive contracts.
When they killed the Archduke, they had no idea what it was going to cause. Neither did anyone else. The various alliance agreements drug one reluctant country after another in the war nobody wanted.
