36 * Check to see if an actor has a treaty forbidding a given action,
37 * and if so, see if the actor wishes to break the treaty.
38 * All applicable treaties are checked. All treaties must be broken
39 * if the action is to be allowed. Propsed treaties are warned about,
40 * but no mention of broken pending treaties are made in the news.
