Beside the military and external challenges, the Gulf Cooperation Council (GCC) countries are facing serious domestic non-conventional challenges, i.e., the demands of political reform, social mobilization, demographic imbalance, environmental deterioration, resource depletion, the transformation and diversification in post-oil economy, terrorism and radicalization etc. In particular one of these new kinds of threats has started to be significant in the last decade. The massive immigration and demographic imbalance between local citizens and foreign residents in countries like the U.A.E, 10 percent; Qatar, 15 percent. This imbalance and the massive immigration into the GCC countries increased the vulnerability of these states, especially since it relates to other critical security issues such as human security (food security for example, in UAE is an example, the country import almost 95 percent of its food consuming) radicalization, energy security, and domestic unrest especially after 2011.
