A handsome, tough-looking boy of nine had popped up from behind the table and was menacing him with a toy automatic pistol, while his small sister, about two years younger, made the same gesture with a fragment of wood. Both of them were dressed in the blue shorts, grey shirts, and red neckerchiefs, which were the uniform of the Spies. Winston raised his hands above his head, but with an uneasy feeling, so vicious was the boy's demeanor, that it was not altogether a game.
"You're a traitor!" yelled the boy. "You're a thought-criminal! You're a Eurasian spy! I'll shoot you, I'll vaporize you, I'll send you to the salt mines!"
Suddenly they were both leaping round him, shouting "Traitor!" and "Thought-criminal!" the little girl imitating her brother in every movement. It was somehow slightly frightening, like the gamboling of tiger cubs which will soon grow up into man-eaters. There was a sort of calculating ferocity in the boy's eye, a quite evident desire to hit or kick Winston and a consciousness of being very nearly big enough to do so. (1.2.15-17)
On the sixth day of Hate Week, after the processions, the speeches, the shouting, the singing, the banners, the posters, the films, the waxworks, the rolling of drums and squealing of trumpets, the tramp of marching feet, the grinding of the caterpillars of tanks, the roar of massed planes, the booming of guns – after six days of this, when the great orgasm was quivering to its climax and the general hatred of Eurasia had boiled up into such delirium that if the crowd could have got their hands on the 2,000 Eurasian war-criminals who were to be publicly hanged on the last day of the proceedings, they would unquestionably have torn them to pieces – at just this moment it had been announced that Oceania was not after all at war with Eurasia. Oceania was at war with Eastasia. Eurasia was an ally. (2.9.3)
The problem is the same for all three super-states. It is absolutely necessary to their structure that there should be no contact with foreigners, except, to a limited extent, with war prisoners and colored slaves. Even the official ally of the moment is always regarded with the darkest suspicion. 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 him 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. (2.9.32, Goldstein’s Manifesto)
