It's very naive and short-sighted when you are not able to see what will happen to Iran if the Americans or anyone else invades Iran, like they did Iraq.
Things will be 1000 times worse than they are now and people will lose what little comforts and security they have left. As usual with us, we will wish that it never happened and we start praying to the memory and grave of the IR regime, wishing it back, like we are doing to another murderer dictator, shah.
This is exactly the situation in Iraq today and it will be even worse in Iran.
