Nuclear weapons only serve as a deterrent to war when both warring nations possess them. If only one nation has them or neither do, a conventional war is still very possible. That is why all of the Cold War wars occurred in third world countries where nuclear weapons were not present. In contrast, the Cuban Missile Crisis (and the corresponding Turkish Missile Issue) did not lead to war between the USA and the USSR specifically because both nations had nuclear weapons which could effectively serve as a deterrent to the other.
As a deterrent.
Nuclear weapons are governed by international agreements such as the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), which aims to prevent the spread of nuclear weapons. Additionally, there are regional and bilateral agreements that regulate the use and possession of nuclear weapons among specific countries. Some countries also have domestic laws pertaining to nuclear weapons possession and testing.
To prevent the spread of nuclear weapons to other nations.
Prevent the spread of Nuclear Weapons related technologies to countries that did not already have them.
Unless you are involved in governmental policy making, which most of us are not, the second best way to prevent the use of nuclear weapons is to raise awareness of the dangers of nuclear warfare and hopefully that will cause sufficient interest so that the government will act accordingly.
Nuclear weapons are a good thing for the United States because they prevent others from using nuclear weapons on the US. In general, the world would probably be a better place without nuclear weapons if it weren't for the fact that they lead to research in all fields of Nuclear Engineering, like Nuclear Power plants and Nuclear Physics. Since nuclear weapons already exist in the world, for the US to get rid of their nuclear weapons would be unwise. Countries that dislike nuclear weapons or even radical terrorist cells and organizations would now have no reason not to launch a nuclear warhead at the US since no retaliation would occur. The strategy of nuclear weapons preventing others from using them against the US is called the Deterrent Strategy.
