Some people believe that intemational sport creates goodwill between the nations and that if
countries play games together they will leam to live together. Others say that the opposite is true :
that intemational contests encourage false national pride and lead to misunderstanding 8nd hatred.
There is probably some truth in both arguments, but in recent years the Olympic games have done

medals .
Incidents of this kind will continue as long as sport is p
