lol minor civs/city states are always more important diplomatically, just like in real life. Countries that are not America, France, England, Germany, China,... etc... ARE basically "city states". Like when Nazi Germany invaded city state Poland and they get minor diplo hits with France and England. Then Germany invaded and puppeted France, taking their capital so then Allies power denounced Germany and went to war. Russia and Allies fight in WW2 together. but immediately afterward Soviets were crazy and become a superpower so America see that as a threat and denounced them and they fight wars on city states ground.
