Why America,UN And Israel Are So Concerned About Iran's Nuclear programme?

You probably don't live in the U.S., so you don't understand that the first thing North Korea or Iran would want to do with a nuclear weapon is to aim itt at us, because they don't like us.

Honestly I'm worried about anyone including my country having nuclear weapons. Why do we need such things? If we've got nuclear weapons though I think its rather hypocritical to think anyone else can't. Maybe they are paranoid of Iran.

The more nuclear weapon each country makes, the more dangerous the world will be. It takes just one country to start a nuclear war and our whole world may be gone within days. The effects of nuclear bomb including its radiation effect can still be felt even today. That's why there is non-proliferation agreement between those countries who already possess nuclear bomb. They cannot make any new nuclear weapons and no new countries should make nuclear weapons.

keep in mind ... israel and iran is the same. but they also actually a silent partner .... they are allied .... until now iran still buy spare parts and weapons made ??in USA through israel .... USA would not have attacked iran, because hindered by Congress .. (Jewish lobby) ... why? Because the Jewish population in Iran is very huge and has a fixed and strong representation in government iran. after all, the founder of Zionist and Shia, are Jewish .... so .. remember .... they both are brothers .... If iran has been strong, the country will be attacked by Iran is 100% arab countries

They are not. They like to rule the world, to lay hands on the treasures of other countries and the only way to do so is to spread fear around the world (own people first + neighbours). This besides of the fact that they all want to write history and war is business. Big business.

Because I think they want to show their not afraid of anyone.

Ganesh, in these days, anyone who have a weapon like a nuclear weapon is like a tickling time bomb. Remember that the last World War II hasn't yet reached a hundred years. There is a good possibility that war can start anytime soon(with tensions and the available technology today, it's not an impossible thing). The US thinks that it in their interest to prevent another World War so it remains (as its allies0 suspicious of countries with this type of weaponry. Weaponry of that kind can easily given into wrong hands and these days, it can kill another a lot of people or used for things that aren't exactly peaceful or democratic. The uS, if I remembered correctly, are usually the last people to declare war but they usually play a vital role so this is I guess for them is a preventive measure. That's my read of it.
