Analyse the ethical dimensions of using nuclear deterrence as a self-defense strategy.

The recent UN Treaty on Ban of Nuclear Weapons has reopened the debate about ethics of nuclear deterrence.

Yes to nuclear deterrence

1. It preserves the global order and prevents wars
2. No major wars have been witnessed since WWII
3. It puts check on regimes like North Korea, who are otherwise unpredictable

No to nuclear deterrence

1. People live in a shadow of fear
2. It is ironic that nuclear armed countries prevent others from building own nuclear deterrence
3. Any possible escalation can lead to a nuclear war, which is a grave crime to humanity
4. Environmental costs of maintaining such a deterrence

It is important for nuclear-armed nations to work together and put an end to their stock. Effort must be made to ensure technology does not fall into wrong hands by establishing a global framework like that for chemical/biological weapons.
