In Fahrenheit 451 you can see several hints that an atomic war takes place. As far I know this topic it's very up to date today, for example when you look to North Korea. Isn't it? Or what do you think?
Fahrenheit 451 has universal themes that definitely carry over time and history. The "war" that destroys cities with its helicopters bombing all over the place is a picture of our current times, the co-dependent nature of the people towards the TV, the lack of sensitivity that they have developed, the distancing from emotional connections, the lack of interest in nature and the morbidity of the "Fire Department" with the consent of the people make you wonder if we are building our own road towards that direction. If you remembber when Sept 11 2001 showed on TV the terrorist attacks in the Twin Towers, many of us watched the implosion of the towers, the people falling from them, and the planes crashing as if it had been a montage made for TV. Many people talked about the desensitized way in which many of us saw the news not because we didn't care, but because our ways of live have become so used to watching things of morbid nature that this came as yet another picture, and that is very scary.
But, concisely, yes, there are themes and symbols in F451 that do show a picture of the future that is both scary and unfortunately quite possible.
The universality is what makes the novel critically aacclaimed and standard reading in any literature or rhetoric class. It's view that a war that has taken place is likely to happen again. It's one of the few things we can count on, and I am sure the author knew that. Destruction is one of the darker sides of humanity, and even now with Kim Jong Il, it looks like there are always despots willing to risk killing themselves for whatever purpose they have in mind.
