Nuclear War

The escalating geopolitical tensions between major powers, the persistence of thousands of nuclear warheads, and decreasing deterrence stability make accidental or deliberate nuclear exchange the most probable global catastrophic event. Climate change amplifies resource conflicts and migration, increasing the risk of miscalculation. Modernization of nuclear arsenals and proliferation of advanced delivery systems heighten the likelihood of a large‑scale strike. A full‑scale nuclear war would cause immediate devastation, nuclear winter, global food shortages, and the collapse of societal infrastructure, effectively ending modern civilization.
