FILE – In this Tuesday, Jan. 27, 2015 file photo, President Barack Obama meets new Saudi Arabian King Salman bin Abdul Aziz in Riyadh, Saudi Arabia. It is not just the Saudi king who will be skipping the Camp David summit of U.S. and allied Arab leaders. Most Gulf heads of state won’t be there. The absences will put a damper on talks that are designed to reassure key Arab allies, and almost certainly reflect dissatisfaction among leaders of the six-member Gulf Cooperation Council with Washington’s handling of Iran and what they expect to get out of the meeting.
