Here is an irony - both Iran's and Saudi Arabia's governments suck and if you visit either be careful. Now, remember, the Sauds are our friends, but, for many who visit there tourists are not very welcome - especially American infidel military. Now, if you visit Iran, and can avoid the govenment and their secret spies most visitors will be welcomed and shown a good time. And they are our enemies. Most of the "protests" and effigy burnings that occur in Iran happen when government workers are "given" a day off and paid to go protest for the cameras.
Personally, I have no desire to visit either nation, not in these times at least. A few decades back I went through Oman and that was not an inviting place.

@Beowulfsfriend True, and they hate one another partly because they worship Allah in a slightly different way

@SeaGreenEyez They are the USA and the UK's political friends. Both countries swap advanced armaments for oil and turn a blind eye to their atrocities

@SeaGreenEyez my use of friends, I thought was clear. They are the US ally. One that I realize is more dangerous than friendly in any manner. I am far from blind on the Saud family and the nation of Wahabbis (the sect of Islam guilty of creating and funding more terrorism in the name of Islam than any others by far.) I could, without looking, give you a laundry list of their evil acts. Putting any trust into them is a fool's errand. They have no respect for the US and view us as their lap dog in the Mideast.

But only of it's secret..smh.
