i hope so. so often humans require common enemies in order to
  band together as one. it's easier when the common enemies are
  other humans, easier still when they're living somewhere else,
  hence nationalism.

  will people band together without hate? perhaps through genetic
  restructuring of some kind.

  will people band together by having a common enemy that isn't
  human or rather, a common enemy that's all-too-human...

  I don't know.
