scenarios of nuclear war

A nuclear war could occur if nations involved in intense conflicts decide to use nuclear weapons, either intentionally or accidentally. It might start from misunderstandings, political disputes, or escalation of conventional conflicts, leading to targeted strikes. Once nuclear weapons are used, their destructive power causes massive casualties, environmental devastation, and long-term radiation effects. The global consequences include severe humanitarian crises, economic collapse, and potential harm to Earth's climate. Preventing such a war relies on diplomacy, arms control, and communication to manage disagreements peacefully and avoid escalation to nuclear conflict.
