It seems certain that the main National Security Challenges affecting Oman are internal rather than external and an attempted
coup d'etat in 2005, which was easily quashed and street unrest in the spring of 2011 and later in 2012, all point to a simmering unrest with the status quo. In early March 2011 HM Sultan Qaboos bin Said al Said decided to replace two key ministers who were seen by many as not keeping in touch with young Omanis not benefiting from Oman's national advances. The long-standing favorite advisor of the Sultan General Ali bin Majid al Maamari was replaced by the relatively unknown and younger General Sultan bin Mohammed al Nua'mani. The current Minister's remit appears unchanged. The Sultanate has also experienced challenges in maintaining its neutrality in the conflict in neighboring
Yemen. It has been accused by its
GCC partners of not being genuinely neutral and favoring the
Houthi rebels. ==Past Palace Office ministers==
