     Some people believe that international sports create goodwill between the nations and that if countries play

games together they will learn to live together. Others say that the opposite is true: those international contests

encourage false national pride and lead to misunderstanding and hatred. There is probably some truth in both

arguments, but in recent years the Olympic Games have done little to support the view that sports encourages

international brotherhood. Not only was there the tragic incident involving the murder of athletes, but the Games

were also ruined by lesser incidents caused principally by minor national contests.

     One country received its second-place medal with visible indignation after the hockey final. There had been

noisy scenes at the end of the hockey match, the losers objecting to the final decisions. They were convinced

that one of their goals should not have been disallowed and that their opponents' victory was unfair. Their

manager was in a rage when he said:"This wasn't hockey. Hockey and the International Hockey Federation are

finished." The president of the Federation said later that such behavior could result in the suspension of the team

for at least three years.

     The American basketball team announced that they would not yield first place to Russia, after a disputable

end to their contest. The game had ended in disturbance. It was thought at first that the United States had won,

by a single point, but it was announced that there were three seconds still to play. A Russian player then threw

the ball from one end of the court to the other, and another player popped it into the basket. It was the first time

the USA had ever lost an Olympic basketball match. An appeal jury debated the matter for four and a half hours

before announcing that the result would stand. The American players then voted not to receive the silver medals. 

     Incidents of this kind will continue as long as sport is played competitively rather than for the love of the

game. The suggestion that athletes should compete as individuals, or in non-national teams, might be too much

to hope for. But in the present organization of the Olympics there is far too much that encourages aggressive

patriotism (爱国主义).
