Protection = duty The first reason that unilateral military force is justified is, the impact of nuclear weapons is dangerous and immorally significant enough to merit the use of military force. Over 200,000 Japanese civilians died during the two nuclear bombs dropped in Hiroshima and Nagasaki. These were the only two detonations of nuclear weapons during a war, in history. Countless other were affected with radiation poisoning, burns, and property damage. Just think of the damage a nuclear war in these modern times could do. This is why nuclear proliferation is evil and must be ended by the United States.
Reason two, nuclear proliferation and detonation accidental or purposefully is imminent. 8 states have successfully detonated nuclear weapons the United States, the Soviet Union, the United Kingdom, France, the People's Republic of China, India, Pakistan, and North Korea. 5 states are in nuclear weapons sharing treaty, Belgium, Germany, Netherlands, Italy, and Turkey. Evidence for the prediction that nuclear accidents are imminent can be found in the case of the Iraqi nuclear weapons program. The UN inspectors found out one other thing about the Iraqi bomb design it is highly unstable. The design calls for cramming so much weapon-grade uranium into the core, they say, that the bomb would inevitably be on the verge of going off even while sitting on the workbench.
