    Countries suspected of developing nuclear weapons:
    - In 2003, the IAEA released a report about Iran's secret nuclear development over a period of 18 years. The report confirms that Iran has produced small amounts of enriched uranium and plutonium. Iran claims that it is developing nuclear power for peaceful reasons, its right under the 1968 Nuclear Non-Proliferation Treaty.
    Iran already has a lot of the building blocks necessary for a nuclear bomb -- such as centrifuges, which are the machines that turn natural uranium into the key ingredient, highly enriched uranium, needed to make a bomb. Iranian officials insist their nuclear program is intended for peaceful purposes. World powers, including the United States, want to curb Iran's nuclear program to keep it from developing a nuclear bomb, and Iran is keen to hold on to as much of its nuclear program as it can.
    - Still has civilian nuclear program.
