When I was a young person, I used to deride writings like 1984 on the grounds that the scenarios and stories presented to carry the message were too far-fetched.

Reading your comment has set off an epiphany, I think I get it now, there probably exists some higher-up person who is thinking along these lines: we must always be in a state of war, for if we are, the populace will want to be ready and willing to fund the instruments of war. And we always want to be ready for war, because if ever we are not, we lose our capability to win a potential future war. For our very survival we must contribute our efforts to build these instruments of war. War is constant. War is peace.
