How we cite our quotes:
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)
Winston again recognizes the switch! Now the Party announces that Oceania is at war with Eastasia, and not Eurasia after all.
