Hello Eva Moon: actually football can unite, but it can enhance and foster divide as well. That the World Cup divides rather than unites nations occur usually either when players of the different countries treat each other badly or if fans have anyway a deep hatred of another nation. They bring the hatred even before the game starts, into the game, but a scene during the play or a stupid comment can enhance this division.
In summary, the world cup divides more than unites, when people (players, supporters, media, managers) behave racist and irresponsible towards each other and explain this bad behaviour as a typical behaviour of that nation, in other words a stereotype. In other words only the stupidity and racism of people make the World Cup divide rather than unite nations (and those people who do divide, actually like it - like the devil likes to divide). More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
