George Orwell said this quote

“ Even the humblest Party member is expected to be competent, industrious, and even intelligent within narrow limits, but it is also necessary that he should be a credulous and ignorant fanatic whose prevailing moods are fear, hatred, adulation, and orgiastic triumph. In other words it is necessary that he should have the mentality appropriate to a state of war. It does not matter whether the war is actually happening, and, since no decisive victory is possible, it does not matter whether the war is going well or badly. All that is needed is that a state of war should exist. ”
