"Our extinction or theirs" is a pretty strong motivator. Lutke did the right thing, IMO.
And this is where we get to the rationalizations...
Understand, I'm making no judgemental pronouncements here. I'm only noting that 'what do we do about the Kafers' is a moral and ethical issue to must wrestled with.
I want to make another point that many of us are missing:
The people of 2300 have significantly different values than we do today. They are more environmentally aware, they're opinions are more unified, and, well, more French. The fulcrum of the world is no long Anglic speaking. For 200 years it's been French, with French conceits, attitudes, leadership and solutions. Some points to remember:
- There is a significant disconnect between the Twilight and 'now'; Much of the knowledge infrastructure was lost in the nuclear holocaust and nobody in 2300 even knows why the Twilight War was fought or who even started it. It is described as an almost 2-century gap in history;
- The people of 2300 understand on a visceral level that humanity almost killed itself and the Earth along with it. Between pollution, nuclear fallout and widespread CBW [chemical and biological warfare] zones, a significant part of the world was rendered uninhabitable and two centuries of cleanup efforts are still ongoing;
- The Kafer represent a vision out of nightmare for an intelligence descended from monkey troops in the Serengeti... The Kafer are vicious and implacable. They cannot be reasoned with, negotiated with, or placated. They must fought, tooth and nail, and the ugly truth is that they're better at it than we are.
- At the end of the Kafer War, ESA nations looked at the wreckage, counted the costs, buried their dead, and then realized that within 10 years [possibly sooner], humanity was going to have to do it all over again. And then 10 years after that, and 10 years after that in ad nauseum;
- And humans like permanent solution. It's wired into our problem solving processes. The idea of that they'd have to fight a life or death battle with the Kafer every half generation was unacceptable.
So what to do?
