For a moment, assume the following, without any proof or evidence just as a thought experiment:
"A country's governing body reflects the average characteristics of people in that country."

It may help if you imagine that the average Iranian is yourself ... or, for that matter, see if you can find those characteristics in yourself and your friends and family. Again, the important point here is detaching from emotions (positive or negative) and trying to understand ...
