The Rand Corporation in a report by Robert J Reardon titled 'Containing Iran: Strategies for Addressing the Iranian Nuclear Challenge' wrote that although the US has relied on special operations against Iran's nuclear program, including sabotage, it has failed to achieve its objectives so far.
It also said that the threats from Israel's nuclear arsenal have not played a significant role in Iran's nuclear decision-making processes.
Israel's nuclear weapons have been useful for Tehran, because Iran said that the West has adopted a double-standard policy towards its peaceful civilian nuclear program, while remaining reticent about Israel's arsenal, the report said.
The report added that although security may be an important factor in Iran's nuclear decision-making, it does not mean that Tehran considers its nuclear program as a deterrent against a possible US attack.
Iran has repeatedly called for global nuclear disarmament, including in the Middle East region where the Zionist regime has stockpiled hundreds of nuclear warheads with open support by the US and its European allies.
Iran, an NPT-signatory, has also called for the removal of all weapons of mass destruction from across the globe.
The UN General Assembly approved a draft resolution proposed by Iran on nuclear disarmament in October 2009 amid strong opposition by the US, Britain, France, Israel and a number of western countries.
The resolution ratified in the first committee of the UN General Assembly calls on all nuclear countries to annihilate their nuclear weapons under the supervision of international bodies.
More than 100 countries, including non-nuclear members of the NAM, voted for the resolution.
The resolution also urges Israel to join the NPT and allow the IAEA to inspect its nuclear installations.
Also in pursuit of global nuclear disarmament, Tehran held a conference on nuclear disarmament on April 18-19, 2010 with officials from different world countries in attendance.
During the two-day conference, world officials, politicians, envoys and nuclear experts from 60 world countries put their heads together to find ways to remove their concerns with regard to challenges on nuclear disarmament, countries' commitment to nuclear dismantlement and disarmament and aftermaths of inaction in the destruction of the Weapons of Mass Destruction (WMDs).
