in my game, i have 5 civs who all declared war against me in the 1930s and 50 years later, none of them wants to be at peace with me. i've never done anything to them except bypassing them for wonder production. they are on other continents. perhaps they are just jealous because i'm leading the game but still i was wondering if there is a way to become friends with them. there is no solution i could find out. it seems like jealousy impairs the AI rationale in civ5.
