Two events in 2008 brought about substantial changes in the international system: the Russian invasion of Georgia and the international financial crisis, both of which highlighted the powerlessness of international institutions to deal with such events. The war in Georgia made it clear that unilateral US measures, including an American deployment in traditionally Russian zones of influence, revitalized the country's relations with the members of the Shanghai Cooperation Organization, in order to propose a regional vision on international security issues. On the other hand, the financial crisis originating in the United States has had repercussions on the world economy, causing, among other things, the volatility of international commodity prices and the retraction of investments in emerging economies. Governments are trying to apply corrective measures ad intra while seeking, externally, to create conditions to stabilize the financial situation from a cooperative perspective. In this context, American hegemony without the multilateralist complement, which means having international legitimacy, is an invitation to generate strategic counterweights. From the perspective of critical realism of geostrategic unilateralism, such as that of the Iraq war, could argue that if the world is to be governed, multilateralism is the way to go.
