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.

Nuclear weapons are weapons which are fueled by nuclear energy. Examples of weapons that can be fueled by nuclear energy are missile warheads and bombs.
Actually this is false most of the Cold War era nuclear weapons have been destroyed.At the peak of the Cold War the U.S. had about 10,000 strategic and 20,000 tactical nuclear weapons and the USSR had about 10,000 strategic and 30,000 tactical nuclear weapons.Following the signing of START both sides agreed to destroy all tactical nuclear weapons and reduce strategic nuclear weapons slowly over a period of time.At this time both the U.S. and Russia have about 3,500 strategic nuclear weapons each and no tactical nuclear weapons (although some people say that Russia secretly maintains about 1,000 tactical nuclear weapons).So, from a peak of about 70,000 nuclear weapons during the Cold War to about 7,000 nuclear weapons now, only about 10% of the weapons then available still remain ready for use.
