Contemporary security threats speak about the non-traditional threats to the nation states. Such a notion of security goes beyond any military action and focuses on the other kinds of threats impacting human existence. It identifies new kinds of threats like terrorism, poverty, human rights violation, human epidemics and migration.
In this context, military action, the usage of force or the usage of nuclear weapons would be considered as the last resort to deal with the new security threats that are confronting the nations today.
a. Contemporary security threats call for active cooperation by the international community. They call for cooperation among the two nation states or at the regional level or may be at the global level.
b. It would involve the international organisations like the UN and its agencies to deal with the global challenges.
c. It would also involve the active support of NGOs like the Green Peace, Amnesty International and Red Cross.
d. Problems like global poverty, migration and environmental degradation, which sought to threaten human existence, cannot be dealt with nuclear weapons. They will need effective resolutions, binding treaties and conventions to get resolved.
e. However, military action can be used to counter terrorist activities, but using nuclear weapons to deal with it would be too extreme, as it would have devastating effects on humanity.
f. Likewise, force can also be used against the regime which is engaged in mass genocide, killing its own people or ignoring the plight of its own population; however, such an action must be endorsed by an international community, which may then impose sanctions against it. For example, the Syrian crisis invoked strong reaction from the international community. Another example can be of the genocide in Darfur where the Sudanese government continued to perpetrate war crimes and inhuman crimes against its own civilians. The UN Peace-keeping mission was deployed but it was obstructed by the government there.
Possessing nuclear weapons may serve as a deterrent in case of a traditional security threat, but using it for defensive purpose can also be a debatable issue. Humanity cannot afford a nuclear war as it would have catastrophic consequences on the world. Also, it would result in a zero sum gain with no winners or losers.
