Delegates walk out of UN general assembly during speech of Ahmadinejad

The UN nuclear Non-Proliferation Treaty (NPT) review conference, which is taking place at the UN right now, hosts delegations from 189 countries, but only a single head of state found his way there today: Mahmoud Ahmadinejad.

Even though Iran's nuclear program is among the hottest topics in international affairs at the moment, Ahmadinejad used his speech at the UN to criticize states which already have nuclear weapons, mainly the USA. When demanding the suspension of members of the board of governors of the International Atomic Energy Agency, Ahmadinejad asked:

"How can the United States be a member of the board of governors when it used nuclear weapons against Japan"

He also accused Israel, which he referred to as the "zionist regime", of secretely building up an arsenal of nuclear weapons.
His speech caused delegates from the US, Britain, Germany and France to walk out of the assembly. The walkout is no surprise as it had even been announced before the assembly took place.
Hillary Clinton is going to speak in front of the assembly later this day. Last week Clinton expressed her hope that the talks with Iran over its nuclear program will be successful:

"If President Ahmadinejad wants to come and announce that Iran will abide by their non-proliferation requirements under the NPT, that would be very good news indeed"
