As someone who spent time in both Iraq and Saudi Arabia in the past few months, I feel that I need to add some comments to this thread, as its not entirely accurate, in my opinion.

Calling Iraq safe and calm is rather inaccurate. Compared to what it was like during the American or ISIS occupation, its certainly far better than it was at any time in the last two decades. However, I have to question what part of the country you visited if you felt it was safe. While ISIS was largely removed from power, they continue to launch strikes several times a week, mostly at night. People are being killed often. Its absolutely not safe at night, particularly in the north (Mosul, and many parts of western Iraqi-Kurdistan). As for southern Iraq, there's a lot of political tension, and unless you are fluent in Arabic, you'd have a very difficult time getting past the huge number of military/militia checkpoints that exist throughout the country.

I'm not saying don't go to Iraq, but definitely do not go there thinking its "safe and calm". While the odds of being harmed are relatively low, they are not zero. This isn't Jordan.

Saudi Arabia is definitely open to tourists for the first time, in most people's lifetime. But the country is not entirely ready for tourism. There's a lot of ignorance, confusion and basic lack of understanding of how tourism works. Most places that I went didn't even understand how to read a foreign passport, and still have no clue what a tourist visa looks like. I had one guy staring at my Sudanese visa from over a year ago, demanding to know why it was expired, because he thought it was my Saudi visa. And to add to that there seems to be fear or concern that tourists are going to either cause problems or get hurt. There were so many places that I visited where I either had some random minder following me about scolding me for doing anything at all, or outright refusing to let me do something like following a clearly labeled hiking trail (Hegra & Al Waha crater).

Absolutely go, but be prepared for some friction.
