Iran

The only realistic demand the UN (or lets say the so called developed nations in the UN) can demand from Iran is not to use nuclear weapons against them without cause or attack Israel and sign some kind of treaty. Iran is a sovereign nation with no corrupt dictator in power. Iran has a unique democracy with religious leaders in control. It is not the ideal because it is less flexible than a government that disconnects from religion. Religion is rigid but at the same time every government in the world borrows ideology from religion. So Iran is currently quite fine and it will be very difficult to impose the will of the western world on Iran. It looks like the western world is waging an unnecessary cold war with the rest of the world. Though many other nations are not opposing western nations openly that is exactly how they must feel.
