Depends on the bomb design and the country. In the US all nuclear weapons now have a PAL (Permissive Action Link) installed. The PAL is a cryptographically controlled device connected to all arming, safing, and destruct systems. The president has a device called the "football" with him at all times, usually carried by an aide. If the president decides a nuclear attack is necessary he uses the "football" to select the plan and it transmits the PAL codes and targeting information. Unless the PAL code is entered by the operators correctly the device will not arm. If they get the code wrong 3 times the PAL refuses all further entries and will not arm. If they persist after 3 bad codes the PAL may choose to destroy the device by detonating the chemical explosives with the nuclear component disarmed.

nuclear deterrence - the idea that if you attack me with nuclear weapons then I will attack you back with nuclear weaponsmutual assured destruction - the idea that if you attack me with nuclear weapons then I will totally destroy you with nuclear weapons and if I attack you with nuclear weapons then you will totally destroy me with nuclear weapons - thus any nuclear attack by either party will result in the certain destruction of both parties
Some of the countries have nuclear weapons because they use them as a defense mechanism. The nuclear weapons are intended to be used whenever there is a war.

In the most basic sense, proliferation of nuclear weapons is the spread of nuclear weapons and weapons usable technology in the world. In a much broader sense, it refers to the acquiring of capability to produce nuclear weapons, or weapons-grade nuclear material (high-enriched uranium, plutonium) by states previously not possessing them.
