The subcritical masses of fissile material are in there, obviously. And there will be the conventional chemical explosives that drive the fissile material together and hold it there for a split second. The triggering mechanism is included with the sensor and control package. Some shielding and reflectors will be in there, and so will some materials that "lock out" the subcritical masses to prevent them "engaging" in the event of an accident. There are a few "security" features within the case of the weapon as well. As security concerns color all aspects of nuclear weapon design and construction, we can only speak to this subject matter in general terms.
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.

Russian nuclear weapons have traditionally had higher yield than US nuclear weapons to compensate for the greater targeting error in their missiles.
The Bikini atoll was used for nuclear weapons testing.
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.
The Non-Proliferation of Nuclear Weapons treaty.

Because the US already had offensive nuclear weapons in Turkey. They saw it as "balancing" things.
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.
Compared to a loaf of bread, all nuclear weapons are heavy. Compared to a truck, some are light and some are heavy.
Things will likely get very messy and unpredictable.
Those that are nuclear, such as the nuclear bombs.

Zambia does not have nuclear weapons.

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.
