Axis of evil
The phrase "axis of evil" was first used by U.S. President George W. Bush and originally referred to Iran, Iraq, and North Korea. It was used in Bush's State of the Union address on January 29, 2002, less than five months after the 9/11 attacks and almost a year before the 2003 invasion of Iraq, and often repeated throughout his presidency. He used it to describe foreign governments that, during his administration, allegedly sponsored terrorism and sought weapons of mass destruction.
The notion of such an axis was used to pinpoint these common enemies of the United States and to rally the American populace in support of the War on Terror. The countries originally covered by the term were Iran, Ba'athist Iraq, and North Korea. In response, Iran formed a political alliance that it called the "Axis of Resistance" comprising Iran, Syria and Hezbollah.
Other countries were later added to the "axis of evil" by US politicians and commentators. The term "axis of evil" is itself a portmanteau of the Axis powers of WWII (Nazi Germany, Fascist Italy, and Imperial Japan).
In 2020s United States politicians have also referred to Big 4 cyber adversaries North Korea, China, Russia, and Iran as the axis.
