The phrase "axis of evil" was first used by U.S. President George W. Bush in his State of the Union address on January 29, 2002, less than five months after the 9/11 attacks, and often repeated throughout his presidency, 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 (Germany, Italy, and Japan) and the Cold War era Evil Empire (the Soviet Union as described by Ronald Reagan).

The State of the Union Address (sometimes abbreviated to SOTU) is an annual message delivered by the president of the United States to a joint session of the United States Congress near the beginning of each calendar year on the current condition of the nation. The State of the Union Address generally includes reports on the nation's budget, economy, news, agenda, achievements and the president's priorities and legislative proposals.The address fulfills the requirement in Article II, Section 3, Clause 1 of the U.S. Constitution for the president to periodically "give to the Congress Information of the State of the Union, and recommend to their Consideration such measures as he shall judge necessary and expedient." During most of the country's first century, the president primarily submitted only a written report to Congress. After 1913, Woodrow Wilson, the 28th U.S. president, began the regular practice of delivering the address to Congress in person as a way to rally support for the president's agenda. With the advent of radio and television, the address is now broadcast live in all United States time zones on many networks.Starting 1981, Ronald Reagan, the 40th U.S. president, began the practice of newly inaugurated presidents delivering an address to Congress in the first year of their term, but not designating that speech an official "State of the Union".
