A、Common people could meet one another at a sport. B、People have no intention to have a contest on sports. C、International sport

How do you know sport at the international level?(26)I am always amazed when I hear people saying that sport creates goodwill between the nations, and that if the common peoples of the world could meet one another at football or basketball, they would have no inclination to meet on the battlefield. Even if one didn’t know from concrete examples, the 1936 Olympic Games, for instance, that international sporting contests lead to hatred, one could deduce it from general principles.(27)Nearly all the sports practised nowadays are competitive. You play to win, and the game has little meaning unless you do your utmost to win. On the village green, where you pick up sides and no feeling of local patriotism is involved, it is possible to play simply for the fun and exercise. But as soon as the question of prestige arises, as soon as you feel that you and some larger unit will be disgraced if you lose, the most savage combative instincts are aroused. Anyone who has played even in a school football match knows this. At the international level, sport is frankly something like warfare.(28)But the significant thing is not the behavior of the players but the attitude of the spectators and, behind the spectators, of the nations. The nations work themselves into angry over these absurd contests, and seriously believe—at any rate for short periods—that running, jumping and kicking a ball are tests of national virtue.
