Space Warfare has already existed, simply not in the form that many think regarding the topic. I believe that Asgardia's future depends on preventing any Earth Nation from spreading their pointless and endless unresolved conflicts of greed and over zealous wants into Space. Could you imagine what future repercussions for Humanity that would have, if Space ended up being heavily contested by separate nations still at war? If you've ever watched the discovery channel theories on other species fighting over influence on earth, it's best to ultimately strive to keep such theories as that, theories. But Humanity needs a revolution, that revolution being Asgardia's sole purpose of providing anyone who wishes to start a new, multi-cultural/ethnic, solely Human civilization, without those destructive lusts that most others have carried since the beginning of time.
Think about it this way. Humanity began with nothing. Eventually, they found out better ways to survive and manage. One example being farming. Eventually, farming became a way to control, because if you control excess food, you can sustain more people, thus you now have a following. Eventually, this gave birth to trading, currency, spheres of influence, power, control. This has sine been the way humans have lived, divided, in different groups, eventually causing wars, and territorial claims which leads us to modern day. Wars, Economics, Trade, all that has simply evolved with technology. We now must find a way to get past that. But it is imperative we establish Asgardia in a way that can also have enough soft power to influence a vast majority of Humanity to also prevent Space Races for wars. I think we have no choice in the matter if we're ever to survive.
