Modern global war, particularly one involving nuclear weapons, would differ fundamentally from earlier conflicts. It would not simply redraw borders or alter political hierarchies. It would place entire societies at risk, potentially reshaping civilization itself. Deterrence theory, arms control agreements, and mutual self-interest are frequently cited as safeguards against such an outcome. Yet even the strongest deterrence systems rely on human decision-making, and history offers many examples of moments when restraint narrowly prevailed—or nearly failed.

As public concern has grown, experts in nuclear history and military strategy have sought to clarify misconceptions. One of the most important clarifications involves the idea of “targets.” Popular imagination often assumes that the first targets in a nuclear conflict would be the largest and most famous cities. While population centers certainly carry symbolic and economic weight, modern nuclear strategy is driven less by symbolism and more by capability.
