'Give Peace a Chance' at the end ?

I finally saw this film after looking for it for decades. Funny that they included the "Lennon-McCartney" credited tune "Give Peace a Chance" at the end of the flick during the end credits ... after showing how the appeasement crowd (peace at any cost) actually CAUSED World War II to come about in the first place,

If you take anything away from the lessons of War it is that you only prevent war by having a strong military NOT by dissolving it.

There will always be a Hitler (or a Putin) out there watching for weakness and then they pounce on the helpless.
