- Award Snub: This short lost an Academy Award to the Silly Symphonies short "The Ugly Duckling". Thankfully, it got better awards later on, like being number 40 on Jerry Beck's list of the 50 Greatest Cartoons.
- Fridge Brilliance: "The flat-footed people started shooting at the bucktoothed people ..." A squirrel would likely only recognize German soldiers with fallen arches shooting up British soldiers with bad teeth; and be totally ignorant of the greater political story behind the conflict. Not to mention misinterpreting a local battle that devastated the region as a world-wide apocalypse.
- "The vegetarians began to fight the meat-eating people..." He might well have seen soldiers in the Indian division of the British army eating only vegetarian dishes before shooting at the Germans in retaliation (Germany is known for its meat dishes and sausages). Again, ignorant of the political context behind the context, the squirrel only saw people killing each other over dietary choice.
- Nightmare Fuel: The war and the humans.
- The last man. After he's been shot, you have the joy of watching him slowly sink into the water, his hand slowly reaching out.
- Some Anvils Need to Be Dropped: It certainly took some courage to speak out against war in 1939, though the U.S. being neutral at the time probably helped. A couple of years later, every animation studio would be producing wartime cartoons that glorified war and demonized the enemy in outrageous and (these days) politically incorrect ways.
- Values Dissonance: When this cartoon was released in December of 1939, much of the world was already at war, and Hitler's persecution of Jews in the Nazi-controlled portions of Europe was swiftly moving towards full-on genocide (Kristallnacht having taken place in 1938). The United States was still neutral, and in retrospect the cartoon can be seen as a call for continued neutrality, a call for America to stay out of Europe's war. Today, the fact that America eventually joined the fight against Hitler (in late 1941) is generally viewed as a Good Thing.
- In addition, the silly reasons for war given in the cartoon — bucktoothed people vs. flat-footed people, vegetarians vs. meat-eaters — don't resonate very well when applied to a war against an actual expansionist, genocidal dictatorship...
- Values Resonance: The cartoon's anti-war message was still relevant enough in the 1950s to warrant a Cold War remake calling for nuclear disarmament.
