I don't have to explain the concept of mutually assured destruction -- or I certainly hope that I don't. If you grew up watching "War Games," you know that when it comes to nuclear war, "the only winning move is not to play."
If you missed out on "War Games," however, you might have encountered Dr. Seuss's 1984 children's tale "The Butter Battle Book." It describes the absurd arms race between two avian humanoid races, the Yooks and Zooks. One prefers their toast butter-side-up, while the other prefers butter-side-down.
They take their butter seriously, you see, and things eventually escalate to the brink of mutual destruction via explosive "Bitsy Big-Boy Boomeroos." If the butter thing smacks of moral equivalence, then I might remind you that despite it's serious message, the book is still aimed at young readers. I also might encourage you to engage your human empathy and dare to gaze beyond whatever moral, political or religious miasma hinders your vision.
Turner Broadcasting adapted "The Butter Battle Book" into a 1989 animated short -- and it's quite good. "Wizards" and "Lord of the Rings" animation master Ralph Bakshi directed and Charles Durning provided the voice of Grandfather. Dr. Seuss himself praised it as the best adaptation of his work, and I'd personally go as far to say that the adaptation punctuates the ending even more effectively. It gives ME chills, at any rate.
Reading the book to my young son also gives me the chills. Most of us were born into this world of nuclear weaponry, into a species stained by the blight of wars innumerable and now the power of the bisected atom. I don't think that, rationally, any of us want that world for our children.
On that note, let's watch "The Butter Battle" again...
