This depends entirely on what you consider to be doing justice. In your hypothetical world, what makes you believe the singular state would function in the same manner as a state in the real world? the needs (minus the obvious) of the people could differ greatly.Just imgine iran is the only country in the world. There is no external influence. Does this system do justice to the people of Iran?
People are always heard, but the issue is whether their voice should or is translated into action by the higher ups.Democracy not about just voting and letting govt to do whatever it want to do for the whole term. It's about people being heard on each level from grassroots to the top.
This is not an only A-->X option. There could be many reasons why X (things not going good for people) is reached. It can be A (Those in power), but it could also be B, e.g what you consider to be good for people may not be good for the long term interests of that country. We can create many scenarios here.If things are not going good for people that means those in power aren't doing their job.
Iranian establishment is following the interest of Iran. This is not a superficially driven motive of image. You need to look at the long term, full picture.People should stand up and tell them to do their job properly. I feel right now the Iranian govt priority is not the people of Iran but the idea of being great in the world.
How do you determine when it a country has become advanced? What is your yard stick?The amount of oil money Iran had it should had made it one of the advanced country in the world.
Oil money is no guarantee of becoming truly advanced. There is a large gulf of difference between being an advanced society and a superficially advanced one. If you want to see this, look across the Persian Gulf to Iran's Monarchial neighbours. Despite their oil money and (unlike Iran)no sanctions to impede them, they are basically just hollow, but gold plated.
Iran is on its way to becoming a very advanced country scientifically and technologically, but due to the forces against it, this is a more difficult road.
