Big Wars: Why Do They Happen and When Will the Next One Be?

World War II was the biggest and most destructive war in history. For two centuries wars had grown ever larger, with the use of more terrible weapons and rising casualties, culminating in the cataclysmic global events of 1939–45. And then, quite suddenly, large international wars have all but disappeared. What caused wars to grow in size to such an extent and then shrink so precipitously? Is this a permanent state of affairs or could big wars make a comeback?
Lawyer and historian John P Storey explores these questions by looking at the evolution of military technology and tactics over the long history of warfare. From ancient bronze spears and chariots to World War II tanks and warplanes, from the nuclear weapons of the Cold War to the drones and robotics of the future, the changes in our methods of waging war has had, and will continue to have, a major impact on their size and destructiveness. The sobering conclusion Storey makes is that, based on past trends and the weapons in the pipeline for the future, there is a much higher risk of there being much bigger wars in the coming decades.
