British House of Commons speech

The phrase evil empire was applied especially to the Soviet Union by U.S. President Ronald Reagan, who took an aggressive, hard-line stance that favored matching and exceeding the Soviet Union's strategic and global military capabilities. 

Reagan's chief speechwriter at the time, Anthony R. Dolan, reportedly coined the phrase for Reagan's use. Some sources incorrectly refer to the June 1982 speech before the British House of Commons as the "Evil Empire" speech, but while Reagan referred twice to totalitarianism in his London speech, the exact phrase "evil empire" did not appear in any speech until later in his Presidency. Rather, the phrase "ash heap of history" appeared in this speech, used by Reagan to predict what he saw as the inevitable failure and collapse of global communism. Ironically, this latter phrase was coined by Bolshevik revolutionary Leon Trotsky in November 1917, using it against his opponents (the Mensheviks) and suggesting that communism was the future; the irony may not have been lost on Reagan's speech writers.
