We have always been at war with Eastasia...
There was, of course, no admission that any change had taken place. Merely it became known, with extreme suddenness and everywhere at once, that Eastasia and not Eurasia was the enemy...The speech had been proceeding for perhaps twenty minutes when a messenger hurried on to the platform and a scrap of paper was slipped into the speaker’s hand. He unrolled and read it without pausing in his speech. Nothing altered in his voice or manner, or in the content of what he was saying, but suddenly the names were different. Without words said, a wave of understanding rippled through the crowd. Oceania was at war with Eastasia!
The next moment there was a tremendous commotion. The banners and posters with which the square was decorated were all wrong! Quite half of them had the wrong faces on them. It was sabotage! The agents of Goldstein had been at work! There was a riotous interlude while posters were ripped from the walls, banners torn to shreds and trampled underfoot. The Spies performed prodigies of activity in clambering over the rooftops and cutting the streamers that fluttered from the chimneys.
But within two or three minutes it was all over. The orator, still gripping the neck of the microphone, his shoulders hunched forward, his free hand clawing at the air, had gone straight on with his speech. One minute more, and the feral roars of rage were again bursting from the crowd. The Hate continued exactly as before, except that the target had been changed.
