When/If Iran obtains nuclear weapons it becomes everyone's problem.
Well, there are plenty of nuclear weapons all over the world, one of the biggest arsenals is in Us and Israel, If you are that much worry you better start with existing threat instead of hypothetical.
additionally, there is a Consensus about our nuclear activity in Iran, all are in same side, it's better to put double standards away and stop bulling others.
yea by killing your own people who protest?
Many Iranians are being heard.
Take care of your people who are dying all over the world because of your intervention in other countries affairs, or your police who beating innocent children in the prisons and streets, or those officers who fired at the flooded people in Catrina those who sickened for help.
You got a messy country, we don't want your help. Afghanistan and Iraq are enough for all the world, take your democracy back for yourself.
Iranian are civilized nation, they know how to solve their problems. We have tasted your messy intervention enough, in Coup against Mosadegh on 19 August 1953, in backing the dictatorship of former regime, in your aides for murdering Iranians at Iraq and Iran war,.....
If we reach to the conclusion that there is a problem, we have proved we know how deal with it. And, also we have proved our unity against foreigner's Interference.
