The countries holding nuclear weapons use them to threaten and threaten other countries. One day, it ignites and the result is very fatal. Take North Korea and the United States as an example. Barack Obama threatened them with the atomic bomb when Kim Jong-under tried to invade Korea. When North Korea was completed, I was afraid and intimidated. Soon, smaller nations will be fed up with being manipulated and unable to retaliate. They may begin to make their own nuclear warheads so that they are not bullied by the greater powers.
Most countries in the world - non - nuclear - weapon states (NNWS) - promised to maintain non - nuclear weapons, including countries that once owned nuclear weapons. South Africa announced in July 1993 that it developed a small weapon before being destroyed in 1991 to join the nuclear nonproliferation treaty as a non - nuclear - weapon state. After a number of nuclear warheads left from the former Soviet Union in the mid 1990s and related transportation systems from Belarus, Kazakhstan and Ukraine returned to Russia, joined the NPT and became NNWS.
After the collapse of the Soviet Union in 1991, Belarus, Kazakhstan, Ukraine inherited nuclear weapons. Belarus has 81 warheads and various non-strategic nuclear weapons. There are 1,410 nuclear warhead missiles in Kazakhstan. Ukraine has 1,900 strategic nuclear warheads and 2,650 to 4,200 nonstrategic nuclear weapons, and it is the third largest nuclear weapon in the world. All three countries signed the Nuclear Non-Proliferation Treaty (NPT), returned the weapons to Russia, and dismantled in the mid-1990s.
Nine countries have nuclear weapons. Five of them (the United States, Russia, Britain, France, China) are members of the official owner club and have made weapons early in the Nuclear Non-Proliferation Treaty (NPT) signed in 1968 and legalized it. The main part dominates international law on nuclear weapons. NPT is very successful. In the 1960s, it seems like the influence on the world stage and the rapid tracking of the position seems to be prompt, so it was widely expected that dozens of countries will set up bombs. However, so far only four fraudulent nuclear weapons states have ignored the "non-proliferation treaty" and created their own bombs. The order of acquisition is Israel, India, Pakistan, North Korea
