in terms of a window you have for timed things, like, say "accept or we will attack" or "will provide military assistance against", do you have any clue of what kind of window do you have for fulfilling your diplomatic obligation? (Obviously sooner is better, do you have any clue where people begin to not believe you?) And also, for "provide military assissance" does that mean you have to initate an attack, or can you provide assissance if the opposing faction attacks you. Does sieging a city (initating, capturing, or simply maintaining a siege) count?

Also, do you have any clue in how canceling treaties affects your diplomatic relations worldwide? (obviously again it hurts your relations with the faction, but I think there might possibly be some minor world-wide negatives).
