Radical Theory derives its views from Marxist Theory. It is therefore sometimes referred to as Marxism, Socialism or Socialists internationalism. Radicals believe that the state is nothing more than a machine for the oppression of one class by another.

But like realists, they see individuals as acting from a kind of rationality; but one that is often distorted by false consciousness regarding their interests through acceptance by the weak of perspectives and values propagated by the strong. Like many liberals, radicals are dissatisfied with the global status quo and hope to transform world politics so as to make the system more equitable and just.
