What is the purpose of nuclear warfare?

The purpose of nuclear warfare primarily lies in deterrence, as nations possess nuclear weapons to prevent adversaries from engaging in aggressive actions due to the fear of catastrophic retaliation. Additionally, some states may view nuclear capabilities as a means to assert power and influence on the global stage. However, the actual use of nuclear weapons is often seen as a last resort due to the devastating humanitarian and environmental consequences they entail. Ultimately, the existence of nuclear warfare raises complex ethical and security dilemmas in international relations.
