I wondered if it was normal that a nation that capitulated, later declares itself to be a free nation again
It doesn't seem to make any sence, since that nation only got one city left, and had a serious technological gap.
Alpha Centauri also has the surrender option, but in that game a nation never seemed to come back on it's decission to undo the surrender, untill it had grown sufficiently strong. But even then it didn't happen so often.( Since both games came from Firaxis ... I thought there would be some logic in there. )
So is this a bug, or just a

deranged AI

?
