I agree with that, I'm surely not the one who's considering Iran harmless. But I consider Saudis not less dangerous. It's just that the Saudis confront less directly with Israel and are "official" allies of the US.

Regarding the Muslims in the former Yugoslavia, I guess you refer to the Muslims currently in Bosnia and Herzegovina, then these "peaceful and modern Muslims" were by necessity "peaceful" during the peaceful periods there as they were a minority since 1878 when Austria got the control over Bosnia. Even in B&H they were under 50% until the last polls. So a lot of them simply grew up secular and didn't care about the Islam books, it's not that the Islam books were different. It seems that the leader of Muslims in the last war was actually advocating for the Islamic state ans Sharia there:

And his government gave the passport to Osama bin Laden too, and brought the Islamic fighters just like in Afghanistan or Syria.
