One world, One Dream! is it possible?

It' s interesting that 2008 Olympics is in communist China.  Because the ancient Olympics were religious festivals. There was a gold and ivory statue of Zeus, by Pheidias, inside the presiding god Zeus' temple at Olympia. 42-feet high, it was one of the seven wonders of the Ancient World.

The first Olympic Games were held in 776 B.C.  and the last in A.D. 393, when the Christian Byzantine Emperor Theodosius I abolished them because they were a remnant of the pagan religions. 

The official motto of the games is "One World, One Dream"! Hmmm, I wonder, what the communist China means by "One Dream"? What dream would that be and if truly the whole world comes together to decide on "One Dream", what would that be? Is it even possible to agree on "One Dream"?
