The evolution of sovereign states around the world has been an uneven process. Some were founded on shared nationhood, language and culture. Some on lines drawn by colonial rulers. Others out of the chaos of war.
But sovereign states have this in common: they are all that now stands between the peoples of the world and utter domination by the transnational monopolies that think the world is rightfully theirs to exploit. The needs of monopolies are simple. They want to be able to shift goods, factories, people and investment anywhere in the world, and they want all countries in the world to sell the monopoly's products – whether it's a physical object like a computer or intangible, like insurance.
