A popular subject
of science fiction is war, most notably war with an alien race.
Works of future war
focus on the nature of the enemy, the weaponry, and tactics.
Dystopia
An ancillary interest
is the aftermath of war, especially nuclear war.
Dystopia (the opposite
of the perfect society characterized by the term utopia) constitutes a
subset of science fiction that focuses on what happens after a nuclear
war devastates the world as we know it.
