No, you're not in fact pointing that out, you're just stating it without providing any evidence at all.
If you're saying 'the goal is to cause suffer according to US officials' surely you'd have a quote for it? You won't because they did not say that and you just stated something not in evidence. Officially, the purpose of the sanctions is to get 'a better deal'.
It's true that Bolton argued war is best option several years before joining this administration, but that's not your claim. Your claim is that he (or some other official) said the purpose of the sanctions is to make the common people suffer, and I can't any statement to that effect.
I understand the importance of being exact, but by being pedantic in a political context without considering motivations and effects is trivialization.
