It all depends upon you point of view: USA and western democracies consider that their ideas are right, and that they have the right to prevent other countries from doing what they want. Iran and other muslim states think that it's the USA and his allies who is wrong, that they do not understand the true faith and that they are being opressed. In fact, the question is only which side can force through the use of military disuasion the other to follow his point of view, and currently that's USA and western allies. It can't be really argued that the US and the NATO have the right to have nuclear weapons and Iran not. The argument of Iran using evetually those weapons to attack the US and NATO force them to accept their ideas is just exactly what the US and western democracies are doing today: Force others to accept their ideas thanks to nuclear and military menace.
My answer to the question is thus not represented here, so I voted yes under UN control. My idea is that any country has the right to use nuclear power for peaceful deveoplement of civil energy to improve the living conditions of his citizens. So as long as Iran accepts any control measures and inspections the UN demands to ensure that the use of nucelar is peacufl, my vote is YES
Don't misunderstand me, if one or the other idea with no justification has to be forced with military strenght, I prefer it to be the USA instead of Iran who determines who and when does what,

, I just wanted to highlight that there is no rational justification for one idea being imposed to others.
