@ Izuul Spoiler : Unlucky. You looked all set to win in the 1440 AD screenshot. Runaway tech leaders are the worst. Could you get to Marines, Flight, and Plastics before Joao's spaceship arrived? Marines and Fighters would at least circumvent the massive diplo penalties which accrue from nuking an AI's friend (Zara's friend, in this case). Also, did you beg or demand gold from HC and Zara Yaqob just before you declared? With 10-turns to cap Joao, you could probably finish the war... at which point your power should have been too high for Zara to declare.
