The Gulf Cooperation Council's New Members

The Gulf Cooperation Council (GCC), made up of six monarchies geographically adjacent within the Arabian Gulf area, invited both the Hashemite Kingdom of Jordan and the Kingdom of Morocco into its organization in May 2011. The timing coincided with the anti-government uprisings in a number of Arab countries including several GCC countries. As the GCC has never previously opened itself up to additional members, the invitations seem to tie themselves to other than economic issues. There are fundamental economic differences between the two invitees and the GCC founding members, but there are two significant similarities; both invitees are Arab monarchies and both have Sunni Islam predominance. Looking at this development from the Religious, Diplomatic, Information, Military, and Economic (R-DIME) instruments of national power of these eight countries, what is the impact of the addition of the two countries for the United States based on how the two invitees and the GCC can integrate with each other?
