In a move that looks — at least on the surface — like an exchange of olive branches, Iran and Saudi Arabia will soon trade diplomatic visits. Iranian Foreign Minister Javad Zarif recently told the semiofficial ISNA news agency that visas have been issued to enable officials from both countries to inspect their respective embassies and consulates. Riyadh and Tehran severed ties last year after Saudi Arabia executed a prominent Shiite leader , Nimr al-Nimr. Meanwhile, Saudi Crown Prince Mohammed bin Salman is rumored to be considering Khalid bin Salman, his 28-year-old younger brother who currently serves as the Saudi ambassador to the United States, as a new minister of foreign affairs. Stratfor sources suggest he would justify replacing foreign policy veteran Adel al-Jubeir by accusing him of taking too hard a line against Iran.
