The war on Terror began on September 11, 2001
This statement has been repeated over and over again, but that does not make it true.
War on Terror is a strange name for a war. Terror is a weapon, not a war. So who is America actually fighting against: Al Qa'ida, an Axis of Evil, all Muslims, the Middle East nations?
Fighting a war against an undefined enemy is dangerous. You do not know who is on your side or when you have won.
This war did not begin in 2001. A new stage may have started, when America was invaded for the first time, but the war did not start then.
Maybe the war began when the CIA overthrew the democratically elected government of Iran in 1953.
Maybe it started when the Western powers chopped up the Middle East to reflect their interests at the end of the First World War.
Maybe it began when the British Army dealt with a revolt in Iraq in 1920-22, more effectively it dealt with an earlier revolt by 13 states in America.
