Relying on the rights of nations to self-determination, we the undersigned demand a referendum, under the supervision of the United Nations, so that the Iranian nation can choose its form of government, thereby discharging its responsibility for its future and alleviating the current crises through collective and effective effort.

Surce here:

The sum of the experiences of the last 40 years show the impossibility of reforming the Islamic Republic, since by hiding behind divine concepts, instrumental use of religion through deception, lack of transparency, ignoring public opinion, subversion of laws and violation of human rights principals, institutional violation of freedom and the fundamental rights of the nation, total incapability of resolving political, economic, social and cultural crises, and obstructing means of legal supervision and pacific reform, the regime has become the principal obstacle to progress and salvation of the Iranian nation.
