There are two versions of nuclear weapons. First, is a fission bomb, which works by blowing apart atoms, and the resulting energy is released. The second is a fusion bomb, which is the opposite of the first, where atoms are smashed together so tightly that energy is released.
Hiroshima and Nagasaki were fission bombs. Tests done at Bikini Atolls were fusion bombs.

A weapon that manipulates the natural alterations of an atom's nucleus to release indescribable amounts of uncontrolled energy in the form of an explosion. Nuclear weapons come in two forms, they are listed in order of energy here.
1. Nuclear fusion: modeled after the reaction that takes place in the sun, it uses tremendous amounts of heat to provide the fusing of lighter nuclei, often Deuterium (or H-2), to form a larger, heavier nucleus, which is, if Deuterium is used, often Hydrogen-4. However the heat used is tremendous, often up to 10,000,000 degrees Celcius. To provide this awesome heat, a small amount of nuclear fission is needed. These fusion explosives are called thermonuclear weapons, and are often compared to MILLIONS of tons of TNT exploding (megatons). Naturally, it does not release any

2. Nuclear fission: does not happen naturally, and is 1/800th the power of a nuclear fusion reaction. It involves the firing of a "neutron bullet" at an atom with an atomic number greater than 91, at which point it splits into two lighter elements, such as U-235 splitting into Krypton-92 and Barium-141, releasing an extra two neutrons, plus the one used to split it. These neutrons move with such speed as to split apart more nuclei. More than a million reactions can happen in a split second, this is called the nuclear chain reaction. These individual atoms release energy that is often compared, in weapons, to tens up to hundreds of thousands of tons of TNT. Nuclear reactions, as these are called, result in the release of deadly radioactive material.

Many countries have nuclear weapons, and the greatest threat to mankind is a nuclear war, which could ultimately result in the destruction of all humans. However, although it may seem that God does not intervene in any major way, I am positive that He would not let such a thing happen.

A weapon that was used on the Japanese to end World War 2, when it hit Nagasaki it killed approximately 300,000 people. Idiot hippies think this was wrong, and apparently never bring up the Batan Death March or the time we hit a German city with conventional B17 bombs and killed 100,000.
We should've rolled on the Soviet Union right after Germany before they had nuclear weapons.

A weapon the united states has a lot of but likes to pretend other countries do when clearly they are too poor to.

A bomb or missile that is packed with explosives and plutonium or uranium to emit radiation.
Terrorists were planning to explode a nuclear weapon over Los Angeles

1)weapon that splits atoms at an exponential rate releasing a fucking shit load of energy and incinerating stupid people and leveling an extremely large blast radius. It also releases an electromagnetic pulse that will shut down power to anything that just didn't take the fucking clue and turn into dust.
