It's nice to see the two leading supporters of global terror groups get into a tussle.
I believe though all of this stems from Qatar not bowing before Saudi Arabia. Independence, even sovereign independence, is not something that is looked at fondly in the region. And Qatar has been really flexing its diplomatic and financial muscle. I was in Doha a month ago, and the infrastructure development is staggering. Can be almost be compared to Dubai, and is way ahead of anything in Riyadh. Add to that Al Jazeera, which has a viewership that is greater than all the other regional channels - combined, and then add Qatar's relationship with Iran.
Anyway, the only 'good' Arab country in that region is maybe Kuwait. At least they allow churches to be built there.
