Hi, I don't know how to cancel a treaty with another civ after 20 turns if they are not taking an initiative. For example, in a game I've been having a trade embargo with one civ against another for 50 turns or so. I would like to end this embargo but I can't figure out how to do that. Of course I could always start a war, but I guess there has to be some other way to do that, too.
