There are 192 governments in the world.
The 192 governments can be categorized into emerging superpowers, superpowers, great powers, regional powers, middle powers, and small powers.
China and India are emerging superpowers (currently the only emerging superpowers in the world). The United States is a superpower (currently the only superpower in the world). Russia, Japan, Germany, France, the United Kingdom, and Italy are great powers. Mexico, the Philippines, Egypt, Iran, Canada, North Korea, Australia, and Israel (among other governments) are regional powers. Uganda, Venezuela, Romania, Cambodia, Greece, Hungary, Sweden, and Jordan (among other governments) are middle powers. Honduras, Serbia, Laos, El Salvador, Slovakia, Panama, and Mongolia (among other governments) are small powers.
According to the realist theory of international relations, a small power cannot affect the international system alone but with some concerted effort a small power can have an impact on the way the system works. According to the realist theory of international relations, it would follow that a great power can affect the international system alone.
Governments appear to be the primary locus of war, i.e. the Iraq War and the Korean War. Emerging superpowers, superpowers, and great powers would seem to have the most influence over wars. Regional powers, middle powers, and small powers would seem to have the least influence over wars.
There are 192 heads of government.
By virtue of being the head of government of a superpower (currently the only superpower in the world), Barack Obama is, perhaps, the most powerful person on earth. The September 11, 2001 attacks indicate that the head of government of a superpower is, perhaps, not the most powerful person on earth. If Barack Obama is not the most powerful person on earth than someone else, perhaps, is the most powerful person on earth. If someone else is the most powerful person on earth than there is, perhaps, an entity that is above the 192 governments. If there is an entity that is above the 192 governments then that entity would be a hyperpower.
There is an entity that is above the 192 governments. That entity is the Illuminati.
The Soviet Union and Nazi Germany indicate that the Illuminati exist.
The Illuminati is a hyperpower. A hyperpower is not a government. A hyperpower is the direct opposite of a small power. A small power cannot affect the international system alone but with some concerted effort a small power can have an (perceived) impact on the way the system works. The Illuminati is the system. The Illuminati control the 192 heads of government. The Illuminati has more influence over wars than all the emerging superpowers, superpowers, and great powers combined. The Illuminati has more influence over every single person on earth (except someone) than all the emerging superpowers, superpowers, and great powers combined.
My theory of international relations (based on the realist theory of international relations) asserts that governments are perceived to be the main power players in international politics.
The 192 heads of government are perceived to be the main power players in international politics. The Illuminati is the actual power player in international politics.
The Illuminati is above Barack Obama. Someone is above the Illuminati. That someone is a power-unto-themself and is thus the most powerful person on earth.
