Answer:
Are you asking about the book by Dr. Seuss?? If so then... ↓
Step-by-step explanation:
It is an anti-war story; specifically, a parable about arms races in general, mutually assured destruction and nuclear weapons in particular. It has been banned at libraries in Canada and America because it satirized the Cold War.
An excerpt says, "The Butter Battle Book is an allegory for the nuclear arms race and the state of mutually assured destruction (MAD) that occurred during the Cold War. This story thus lends itself to a discussion with children about the concept of war itself, the moral issues related to war and the outcomes of retaliatory acts."
I hope this helped!
Have a nice day :)
