No two democracies have gone to war, ever, and that's an important indicator of our future. Don't get me wrong, we have A TON of human rights, poverty, and equality problems, but things are rapidly improving directly proportional to our technical capabilities.
By the time we can even construct two ships capable of having a realistic fight in space we're more likely to send them exploring rather than duke it out. All current governments even capable of dreaming of getting in to space work together on the problem, sharing resources and knowledge.
To recap, we'll never go to war in space. I also doubt any other intelligent life with the capabilities to do so will need to attack us because they've solved any problems requiring them to do so.
