That is why I do not anticipate a massive world war.
Modern warfare will likely take the form of conflicts between nations, and these wars will be protracted. While the rivalry might subsequently continue in the commercial and technological spheres, I am certain that they do not want these conflicts to escalate into a full-scale war.
Indeed, currently the physical war is localized to a few conflicts. The rest - commercial, technological, psychological, political, name it - is going on, heavily, under our noses. Far too many people are already part of it and don't understand.
But I am not as optimistic as you are on the full scale war. I do hope we will not get there, but we are incredibly close to it
