Playing a bloodlust game and made an ally of nearest AI (Germans) early on to provide buffer zone against large AIs. Knocked out all the other civs now, just got the Germans left. Need to cancel alliance in order to knock them out. Trouble is they won't talk to me!!! Schoolboy error I know, but I want to end the game now, rather than ditching it. Does anyone know any sure fire techniques to get a substantially weaker ally to talk to you, when they 'know' you're just going to obliterate them? Thanks in advance for any words of wisdom.
