The reason Western nations are afraid of Iran possessing nuclear weapons is that the Iranian government has made consistent statements that Israel will vanish from the page of history and supported Islamist paramilitary/terrorist groups like Hezbollah and Hamas which are organized to achieve that end. Additionally, Iran signed the NPT while Israel and Pakistan did not, meaning that Iran has certain treaty obligations and benefits whereas those other states do not.
no
In the most basic sense, proliferation of nuclear weapons is the spread of nuclear weapons and weapons usable technology in the world. In a much broader sense, it refers to the acquiring of capability to produce nuclear weapons, or weapons-grade nuclear material (high-enriched uranium, plutonium) by states previously not possessing them.
No, but it would be nice to see them have nuclear weapons, considering that Pakistan and India are nuclear nations.
There were tests of nuclear weapons but no other nuclear weapons were dropped on other nations as an act of war. Hiroshima and Nagasaki are the only uses of atomic weapons on other nations.
While it is believed that Israel has possessed nuclear weapons since 1975, they neither deny nor admit to possessing any. It's widely believed that they are a nuclear power, although they have stated they will not be the ones to introduce nuclear weapons to the Middle East.
Nuclear weapons are typically created and declared by countries that have developed the capability to produce them. Declarations of possessing nuclear weapons are often made by official government leaders or through public statements from a country's nuclear program authorities.
Basically if you have nuclear weapons, I can really tell that your enemies do not want to mess around with you. If they mess around with you and want to destroy your country, you can nuke their whole entire World.
Yes hence the word NUCLEAR WEAPONS
If western nations do not step in and help warlords will over throw democratic- u.s. supporting nations and replace them with tyrannical anti west governments that want nuclear weapons.
As far as I know nuclear weapons have never been traded between countries, so if a country has nuclear weapons it is due to their own science and technology, or to espionage activities to get the required knowledge. The other criterion is not to have signed up to the Non Proliferation Treaty, except for countries that had already developed weapons when the Treaty came into being.
Any answer to this question would be pure opinion, but I sincerely believe that nations should not have the freedom to develop nuclear weapons. The more nations that have them, the more likely it becomes that they will be used.
To prevent the spread of nuclear weapons to other nations.
