I sympathize. I'm not exactly enthusiastic about more land past the edge of our administrative range, either.
On the other hand, a Genius told us to do it. And Geniuses are Magic (or sufficiently advanced narrativium, which is functionally indistinguishable from magic). The last time a Genius told us to do something, we thought it was stupid, but it turns out that it would have "coincidentally" saved us from multiple crises. The time before that, we did it and then a meteor fell on our enemies. So... even if there are major qualms to be had about the decision, I'm voting with the Genius.
