Iran President Mahmoud Ahmadinejad restated his opposition to nuclear weapons at the Nuclear Non-Proliferation Treaty (NPT) conference this week. But analysts say that an Iran capable of building a nuclear bomb is something that the US may have to get used to.
The Non-Proliferation Treaty was designed to limit the acquisition of nuclear weapons to five countries who already had them. But now four more states have joined the nuclear club – an 'erosion' of the treaty that could spell its doom.
Iran says the 10 new nuclear sites are for energy, not weapons, but sent mixed messages on whether it will remain in a member of the Non-Proliferation Treaty.
Washington warns of new sanctions after a UN report says Iran is expanding nuclear enrichment activities.
