This is an indication that the Saudis may well be serious about cutting off funding to jihadis (which they signed an agreement to do when Trump visited).
In addition to the Saudis, Egyptians and Bahrain cutting ties with Qatar, the body of the article reports that the UAE did as well - all today. The UAE only gave Qatari diplomats 48 hours to clear the country.
Saudi Arabia is Qatar’s only link by land, and the UAE is it’s closest neighbor by sea (which includes Dubai, the main economic and cultural hub of the region).
There is a lot of business that takes place (and family ties) between Qataris, Saudis and Emiratis. This is a big move in the region.
So what is the end game here? I am missing it and am surprised how this happened so quick. Normally, this would be a prelude to war, but the Saudi can’t fight their way out of a paper bag. Attacking Yemen was a disaster politically and militarily.
