hence the good-faith but non-binding claus. E.g. I wouldn't call someone pulling douche-bag move using the letter of the agreement as good faith and would happily backstab them. Being polite to the rude is not being polite, it's just being weak, same applies to excercising good faith to a Machevelli. (I'm not bashing on Machy style, as I do condone many of its value and tactics!)
I tend to otherwise treat good faith with good faith though (I find it hard to backstab someone who has been a good ally, but alas, all good things must end but I think I'd follow the declaration clause in a NAP rather then surprise attack someone who allied in good faith), a weakness I'm sure in some cases but also an advantage in many others.
Maybe there's an evil machy in me somewhere I just haven't discovered yet
