Generate text that refutes this claim: Public acknowledgement of the right to nuclear deterrence will benefit the public regulation of nuclear weapons generally  When nuclear deterrence is an acknowledged right of states, they will necessarily be less concealing of their capability, as the deterrent effect works only because it is visible and widely known. Knowledge of states’ nuclear capability allows greater regulation and cooperation in development of nuclear programs from developed countries with more advanced nuclear programs. [1] Developed countries can help construct and maintain the nuclear weapons of other countries, helping to guarantee the safety protocols of countries’ programs are suitably robust. This will cause a diminution in clandestine nuclear weapons programs, and will reduce the chances of weapons-grade material falling into the hands of terrorists. Thus, greater openness and freedom in the development of nuclear weapons will increase the security of nuclear stockpiles.  [1] Sagan, Scott D. 1993.

defence house believes all nations have right nuclear weapons
It is very unlikely that many states will invite their neighbours to help them in the development of their weapons and in securing them, as doing so would open the risk to sabotage and would disclose potential weakness in their defences. Furthermore, terrorists will not be substantially deterred by greater openness in weapons development, as there will be more potential suppliers of weapons.
