Let us face the facts: Iran is not North Korea and it doesn't depend on the West for its food or any other needs. Therefore, no sanction against Iran will be successful. Western nations just don't have anything that Iran wants, and so they can't employ carrot and a stick strategy. It just won't work in this case. Even if Iran builds a bomb, what of it? Half the world has nuclear capability and we don't see them sparking armageddon. Let us see the countries that are so adamant to prevent Iranian nuclear development: USA; nuclear powerhouse capable of blowing the whole planet ten times over, Israel; we can only guess how many bombs they have, but they are, just like Pakistan, allies of the USA, and therefore eligible to possess nuclear arms. Many countries, like India, also possess WMDs. Let us not be hipocrites. What gives these countries the right to have what Iran can't? Apply the same rules to everyone, and then you can demand the same of countries like Iran.
