Iran. Saudi Arabia. Axis of Evil.

It was around 14 years ago that President Bush (2) famously declared that Iran, among others, was part of an axis of evil. All the while there were high level friends and allies from Saudi Arabia egging him on to invade Iraq.Today Iran seems a bit less evil and Saudi Arabia, again, seems way more like ISIS than before. They've executed a Shiite cleric that is anti ISIS.Iran erupted in outrage. I would as well.Now Iran isn't a stronghold of rights. People do go to prison for advocating the wrong ideas. Yes, they also execute people. Pointing with bloody fingers at Saudi Arabia for doing the same.What, exactly, makes Iran any worse than Saudi Arabia?
