Late last February, after six world powers and Iran wrapped up nuclear talks in Almaty, Kazakhstan (Feb.26-27), two members of the U.S. nuclear negotiating team secretly flew to Oman where they rendezvoused at a beach-front villa with two American officials who had arrived from Washington.
Deputy Secretary of State William Burns and Jake Sullivan, Vice President Biden’s national security advisor, flew to the Arabian Sea port of Muscat from Washington. White House Iran advisor Puneet Talwar and State Department arms control advisor Robert Einhorn flew to Oman from the Almaty nuclear talks.
