The perception that Iran has been acquiring nuclear weapon is very much disturbing for its Arab neighbors, particularly Saudi Arab and Egypt. Indeed, Iran’s nuclear program having military dimension would jeopardize the regional balance of power. The deterioration of existing balance of power would unleash the arms race in the region. Saudi Arab and United Arab Emirate have already been spending a colossal amount of money on the conventional weapons. The security observers believe that Iran’s nuclearization would have domino effect on the entire region. There are ample chances that a few Arab states leave the NPT and develop nuclear weapons to balance Iran.
The differences between Iran and Western countries have been increasing. Recently, the United Kingdom Embassy in Tehran was stormed by Iranian protestors due to London’s accusation that Tehran was developing nuclear weapons. The rowdy mob attack on the British Embassy multiplied the anger of the Western nations. On November 30, 2011, British Foreign Secretary William Hague stated in the parliament: “If any country makes it impossible for us to operate on their soil, they cannot expect to have a functioning embassy here.” Subsequently, Britain had closed the Iranian embassy in London and asked all of its diplomats to leave the country immediately on December 2, 2011.
In the recent high-profile Gulf Forum 2011 (The Gulf and the Globe) jointly organized by the Institute of Diplomatic Studies of the Ministry of Foreign Affairs, Saudi Arab and Gulf Research Center of the UAE at Riyadh from December 3-5, 2011, the Arab leaders had expressed their serious concerns over the Iran's hostility toward the West. They also claimed that Iran’s nuclear obsession would destabilize the region. The leaders of GCC countries at the forum demanded that Iran should refrain from developing nuclear weapons.
To conclude, Tehran’s increasing differences with the Western powers and Gulf Cooperation Council countries would have severe repercussions for the regional stability. It would further widen the gap between Iran and GCC countries and also justify extra regional powers to intervene in the region.
