Generate text that refutes this claim: All countries have a right to defend themselves with nuclear weapons, even when they lack the capacity in conventional weapons  The nation-state is the fundamental building block of the international system, and is recognized as such in all international treaties and organizations. States are recognized as having the right to defend themselves, and this right must extend to the possession of nuclear deterrence. Often states lack the capacity to defend themselves with conventional weapons. This is particularly true of poor and small states. Even wealthy, small states are susceptible to foreign attack, since their wealth cannot make up for their lack of manpower. With a nuclear deterrent, all states become equal in terms of ability to do harm to one another. [1] If a large state attempts to intimidate, or even invade a smaller neighbour, it will be unable to effectively cow it, since the small state will have the power to grievously wound, or even destroy, the would-be invader with a few well-placed nuclear missiles. [2] For example, the Russian invasion of Georgia in 2008 would likely never have occurred, as Russia would have thought twice when considering the potential loss of several of its cities it would need to exchange for a small piece of Georgian territory. Clearly, nuclear weapons serve in many ways to equalize states irrespective of size, allowing them to more effectively defend themselves. Furthermore, countries will only use nuclear weapons in the vent of existential threat. This is why, for example, North Korea has not used nuclear weapons; for it, like all other states, survival is the order of the day, and using nuclear weapons aggressively would spell its certain destruction. Countries will behave rationally with regard to the use of nuclear weapons, as they have done since their invention and initial proliferation. Weapons in the hands of more people will thus not result in the greater risk of their use.  [1] Jervis, Robert. 2001. “Weapons Without Purpose? Nuclear Strategy in the Post-Cold War Era”.

defence house believes all nations have right nuclear weapons
While states do of course have the right to defend themselves, this does not extend to the possession and use of nuclear weapons. The destructive power of nuclear weapons cannot be contained in either space or time. They have the potential to destroy all civilization and the entire ecosystem of the planet. International humanitarian law prohibits the use of weapons that are incapable of distinguishing between civilian objects and military targets. [1] Indeed, the use of nuclear weapons could well constitute a war crime or a crime against humanity. [2] Just as biological and chemical weapons are banned by international treaty, so too the international community generally acknowledges the dangers of nuclear proliferation, which is why so many treaties are dedicated to non-proliferation. [3] It is unfortunate that nuclear weapons exist, even more so that a few countries are still seeking to develop them. It is better to fight this movement and to prevent their use or acquisition by terrorists and the like. It is also essential for States to fulfil their obligation under Article VI of the NPT ‘to pursue in good faith and bring to a conclusion negotiations leading to nuclear disarmament in all aspects under strict and effective international control’. [4] Nuclear weapons cannot lawfully be employed or deployed and there is a legal obligation to negotiate in good faith for, and ensure, their elimination.
