You mean this to be "You wish merely that we escape our enemies," correct? In other words, the person addressed might wish for more, but doesn't. As opposed to {'e' DajIn neH} "You merely wish that...," implying perhaps that he should be doing more than just wishing.
Why not put {neH} after {manargh} if you mean the former? But interesting question, is there any reason not to put {neH} after the pronoun?
