That is true. Though it is slightly different, since in TFA he says, “I will let nothing stand in our way.”
I think the inflection of “You don’t have to say anything” doesn’t fit as smoothly with the rest of the dialogue as “Nothing will stand in our way” does. Like, it carries this attitude that the rest of his monologue doesn’t have, if that makes sense. Though just looking at the dialogue I don’t think there’s anything wrong with it.
