There are no clear-cut answers here. The whole question of the campaign is whether the UEF is too optimistic or the GTVA too cynical.
That's the whole point of the story.
Nehemiah has a great point. I find it incredibly difficult to believe that human society would ever turn into such a pacifist state. Man has excelled at killing man since early history. That violent nature will never change on man's account alone.
Again, that's the question, isn't it?
Are we really to believe that after being cut off from her colonies for less than a century, Earth is overtaken by wimps?
An Elder might ask you why you think that someone who has the strength to say 'no' to murder is a wimp. When killing is the easy decision, the killers are the cowards, the Elder might suggest.
Don't get me wrong in any of what I'm saying. I think that Blue Planet is a great set of campaigns and a great storyline. I just feel that it would do better without all the Hinduism and Eastern religion mixed into it.
How would one side of the struggle be presented, then?
The UEF is, in many ways, a state built on applied psychology. It is an attempt to create a society in which individuals can be truly moral instead of being forced to compromise their beliefs to serve the situation. It is a state which believes that the ends do not justify the means.
It seems ill-advised to engage in a campaign that weakens both parties to the point of vulnerability TO the Shivans. That clearly defeats the GTVA's supposed altruistic goal.
No, it doesn't. The GTVA war was launched because they feared the alternative was the collapse of the Alliance.
I suggest checking out the dossiers on the BP website.
