Generate text that refutes this claim: Possessing nuclear weapons will be counter to the peaceful interests of states  Most states will not benefit at all from possessing nuclear weapons. Developing a nuclear deterrent is seen in the international community as a sign of belligerence and a warlike character. Such an image does not suit the vast majority of states who would be better suited focusing on diplomacy, trade, and economic interdependence. [1] The loss of such diplomatic and economic relations in favour of force can seriously harm the citizens of would-be nuclear powers, as has occurred to the North Koreans, who have been isolated in international relations by their government’s decision to develop nuclear weapons. If the right to nuclear weapons were recognized for all states, only those states that currently want them for strategic reasons will develop them, and they will do so more brazenly and with greater speed. These countries might try to develop them even if proliferation is outlawed, but giving them license increases the likelihood that they will succeed. Furthermore, when countries develop nuclear weapons, their neighbours may feel more vulnerable and thus be compelled by necessity to develop their own weapons. This will lead to arms races in some cases, and generally harm diplomacy.  [1] Sartori, Anne. 2005. Deterrence By Diplomacy. Princeton: Princeton University Press.
defence house believes all nations have right nuclear weapons
It is true that most states will not develop nuclear weapons, whether they are recognized as a rightful possession of states or not. The important thing is that those states that do want nuclear weapons can have them, which will likely be only a handful. As to arms races, it is unlikely that they will occur, as the defence pacts between many states, such as NATO defend non-nuclear states without requiring them to possess such weapons themselves. [1] Furthermore, if a state feels vulnerable due to the nuclear armament of its neighbours, it should absolutely have the right to defend itself.  [1] Sagan, Scott D. 1993.
