Kerry is simply carrying water for the administration. Their negotiations have gone on for at least a year or two...meaning neither Kerry or Clinton really were part of this effort. At some point, the public will figure out that the White House did much of the homework themselves for this entire episode. Duped? They simply didn’t believe the reports, and kept blind to the fact that they could be used (yes, they are that naive).
As for the outcome? The Saudis will not allow this entire episode to go beyond a certain point. If they have to buy weapons from France or Russia to ensure the Iranians are kept under control....fine, they will do so. The Russians already have this plotted out like some WWE-wrestling match. They see a weak Saudi Arabia, willing to buy all kinds of military toys, and then become a monthly customer.
Makes sense to me.
The Saudis will use their POCKET CHANGE to buy necessary weapons.
