It is not denying the fact that dialogue is the best way to win without fighting, but can you give any example of it. Is there any great nation of the world who have won without fighting. I think you dont have any example of it. Thus there is only point of view about the essay that " There is no nation who have won without fighting."
For this you have many examples in the history.
