The Indomitable Human Spirit in Your World
How do you write the “indomitable human spirit”, if you have it?
My take. Some of the aliens or fantasy species in my worlds don’t have the same “never giving up” that humanity does. The aliens have a tendency to give up more easily. On the one hand, this means that they get unified faster; a conqueror can likely unify most alien species quickly, but cannot do the same for humanity, which will resist tooth and nail. This means that humanity can guerilla war against any alien conqueror. On the other hand, planetary unification amongst most alien species has allowed them to take to the stars more easily, not being burdened by internecine rivalry. Sometimes you have empires of multiple alien species, all ruled by a single government.
So basically Humanity in my hypothesized Science Fiction project, "Worlds of Beyond" is basically Space Afghanistan. Seen as a backwater with warring groups of people, but anyone who tries to deploy a military to it inevitably runs out of political will (compared to humanity) and fails. (And no, you can’t win only by bombing. The Vietnam War proved that. Orbital bombardment is the bombing equivalent.)
