Too Close to Reality...

"War prisoners apart, the average citizen of Oceania never sets eyes on a citizen of either Eurasia or Eastasia, and he is forbidden the knowledge of foreign languages. If he were allowed contact with foreigners he would discover that they are creatures similar to himself and that most of what he has been told about them is lies. The sealed world in which he lives would be broken, and the fear, hatred, and self-righteousness on which his morale depends might evaporate. "

George Orwell, 1984
