Nuclear weapons in the world

If we analyse the countries which possess nuclear weapon, we can divise it in three groups.

The fisrt one is the states which are a part of NPT (nuclear no-proliferation treaty), in order of aquisition of nuclear weapon these are: United States, Russia, United Kingdom, France and China. This countries have nuclear weapons but they apply the policy of the treaty.

United States and Russia are the most importante owner of nuclear weapons, they possess more than 5000 nuclear weapons activate.

Then we have the countries we have nuclear weapons but which never sign the NPT. In this group we can find India, Pakistan and North Korea. North Korea had been a party to the NPT but withdrew in 2003. There is also the case of Israel. According to some testimonies this country would possess many nuclear weapons (Approximately 200) ,but Israel denies it.

In the third group we can find Iran, Brazil, Saudi Arabia, Syria and Algeria. This states are suspected of being in the process of developing military nuclear programs.

Algeria possessed nuclear weapon but France dismantled it before the independence in 1962.

Brazil is developping nuclear program with cooperation of Argentina but he is suspected to develop a program to possess nuclear weapon.

Saudi Arabia would have done an agreement with Pakistan to have nuclear technology in exchange of petroleum.

Iran want to develop civil nuclear program, but the states which signed the NPT think that it wants also develop military nuclear program. Especially since Iran is surrounded by state possessing nuclear weapons (Israel and Pakistan) and so it feels threatened.
