There are days when all it takes is a single speech to illustrate the decline of a world power. A face can speak volumes, as can the speaker's tone of voice, the speech itself or the audience's reaction. Kings and queens have clung to the past before and humiliated themselves in public, but this time it was merely a United States president.

Or what is left of him.

George W. Bush has grown old, erratic and rosy in the eight years of his presidency. Little remains of his combativeness or his enthusiasm for physical fitness. On this sunny Tuesday morning in New York, even his hair seemed messy and unkempt, his blue suit a little baggy around the shoulders, as Bush stepped onto the stage, for the eighth time, at the United Nations General Assembly.

He talked about terrorism and terrorist regimes, and about governments that allegedly support terror. He failed to notice that the delegates sitting in front of and below him were shaking their heads, smiling and whispering, or if he did notice, he was no longer capable of reacting. The U.S. president gave a speech similar to the ones he gave in 2004 and 2007, mentioning the word "terror" 32 times in 22 minutes. At the 63rd General Assembly of the United Nations, George W. Bush was the only one still talking about terror and not about the topic that currently has the rest of the world's attention.

"Absurd, absurd, absurd," said one German diplomat. A French woman called him "yesterday's man" over coffee on the East River. There is another way to put it, too: Bush was a laughing stock in the gray corridors of the U.N.
