Nuclear War

Current geopolitics are marked by renewed great‑power rivalry, with the United States, Russia, and China modernising their nuclear arsenals and deploying new delivery systems. Regional conflicts in Europe, the Middle East, and East Asia raise the odds of accidental or intentional escalation, and early‑warning systems remain vulnerable to false alarms. A single miscalculation could trigger a full‑scale nuclear exchange, injecting massive amounts of soot into the stratosphere, blocking sunlight, and collapsing global agriculture. The resulting nuclear winter, widespread starvation, disease, and societal breakdown would likely end modern civilization and could threaten the very survival of humanity.
