Quick ! what does it mean to you when it says "peace cannot be kept by force, it can only be achieved by understanding

Peace cannot be kept by force; it can only be achieved by understanding. ... Please realize that understanding does not mean agreement. You can understand someone, their comments and their motivations ... If it helps, like a salve for your ego, many say that it takes a better person to take that first step.

In paragraph 47, it says “moments like these make a pioneering flight anything but dull” i’d say he’s optimistic and determined? ? and in 48, it describes how i’m assuming people he looks up to walked the same path so maybe he’s honored to be on the journey ? sorry if i’m wrong.
