World War II is one of the most studied and retold events in human history.

Yet many persistent myths continue to shape how we understand the conflict, fueled by propaganda, pop culture, and oversimplified narratives.
Here are 10 of the most common claims, examined for their truth or fiction.
Hitler Was a Military Genius

False
Also read
Although Hitler saw early victories, many of his strategic decisions were reckless.
His insistence on holding Stalingrad, against the advice of his generals, ended in disaster. Far from a genius, his military interference often undermined the German war effort.
D-Day Won the War

False
D-Day was crucial for the Western Front, but the Eastern Front had already inflicted massive losses on Nazi Germany.
The Soviet Union’s pressure was decisive, and without it, the Normandy landings may never have succeeded.
The Allies Had No Knowledge of the Holocaust

Partly False
By 1942, reports of mass killings had reached the Allies, though many doubted their scale.
The Holocaust wasn’t a central war aim, and it wasn’t until the liberation of the camps that the full horror became undeniable to the world.
Pearl Harbor Was a Total Surprise

Partly False
The attack was shocking, but not entirely unforeseen.
Intelligence suggested a Japanese threat, but poor communication and a failure to act on warnings meant the U.S. was unprepared when the strike came on December 7, 1941.
Mussolini Was Hitler’s Equal Ally

False
Though Mussolini dreamed of glory, Italy was militarily weak and more of a burden than a help to Nazi Germany.
Hitler often had to rescue Mussolini, and Italy never played a decisive role in the overall outcome of the war.
The Atomic Bombs Alone Ended the War

Partly True
The bombings of Hiroshima and Nagasaki were pivotal, but Japan was already under immense pressure.
The Soviet invasion of Manchuria also dealt a major blow and likely influenced Japan’s surrender as much as the nuclear attacks.
The War Was Only Fought in Europe and the Pacific

False
World War II was truly global. Fighting took place in North Africa, the Middle East, the Arctic, the Atlantic, and even in parts of South America and Asia.
Many of these battles are underrepresented in Western narratives.
All Germans Supported the Nazis

False
While many did support Hitler, significant resistance existed.
Groups like the White Rose, various religious dissidents, and even military officers plotted against the regime, including the failed July 20 plot to assassinate Hitler.
Germany Could Have Won the War

Partly True
This is one of the most debated hypotheticals. If Germany had not invaded the Soviet Union or had developed nuclear weapons first, the outcome might have been different.
However, the Allies had superior resources, and time was working against the Reich.
