I think to some extent, the problem in Saudi Arabia is with individuals, those individual donors, etc. but not so much with the Royal Family, the Rulers. This may be in part what BigUn is referring to. I see it as something that we need to find out definitely what is happening.
Yes, Saudi Arabia exports radical teaching across the globe and funds Mosques the world-over. This needs to be dealt with.
Yes, it is said Saudi Arabia is white Daesh, ISIS is black Daesh but the two follow some of the same teachings on religion.
Just my opinion.
I'm not so sure about the dangers of Iran, they are an enemy of Israel; that is certain. After that, I'm a bit unsure.
