The phrase is derived from that of the rogue state, but the term itself is reminiscent of the Axis Powers of World War II and of President Ronald Reagan's evil empire designation for the Soviet Union.

Bush's exact statement was as follows:

[Our goal] is to prevent regimes that sponsor terror from threatening America or our friends and allies with weapons of mass destruction. Some of these regimes have been pretty quiet since September the 11th. But we know their true nature. North Korea is a regime arming with missiles and weapons of mass destruction, while starving its citizens.

Iran aggressively pursues these weapons and exports terror, while an unelected few repress the Iranian people's hope for freedom.

Iraq continues to flaunt its hostility toward America and to support terror. The Iraqi regime has plotted to develop anthrax, and nerve gas, and nuclear weapons for over a decade. This is a regime that has already used poison gas to murder thousands of its own citizens—leaving the bodies of mothers huddled over their dead children. This is a regime that agreed to international inspections—then kicked out the inspectors. This is a regime that has something to hide from the civilized world.

States like these, and their terrorist allies, constitute an axis of evil, arming to threaten the peace of the world. By seeking weapons of mass destruction, these regimes pose a grave and growing danger. They could provide these arms to terrorists, giving them the means to match their hatred. They could attack our allies or attempt to blackmail the United States. In any of these cases, the price of indifference would be catastrophic.
