"September 11 was terrible, but if one goes back over the history of the IRA, what happened to the Americans wasn't that terrible," the Nobel Literature Prize winner told the leading Spanish daily El Pais.

"Some Americans will think I'm crazy. Many people died, two prominent buildings fell, but it was neither as terrible nor as extraordinary as they think. They're a very naive people, or they pretend to be."

Lessing had sharp words for both President Bush and his ally, former British premier Tony Blair.

"I always hated Tony Blair, from the beginning," El Pais quoted Lessing as saying. "Many of us hated Tony Blair, I think he has been a disaster for Britain and we have suffered him for many years. I said it when he was elected: This man is a little showman who is going to cause us problems and he did."

"As for Bush, he's a world calamity," added Lessing. "Everyone is tired of this man. Either he is stupid or he is very clever, although you have to remember he is a member of a social class which has profited from wars."

Iran also came in for a lashing from Lessing, who was born to British parents who were living in what is now Bakhtaran, Iran.

"I hate Iran, I hate the Iranian government, it's a cruel and evil government," she was quoted as saying.

"Look what happened to its president in New York, they called him evil and cruel in Colombia University. Marvelous! They should have said more to him!"
