Was Stalin truly so naive that he didn’t believe Germany would attack? Or did he know but chose to “look the other way”? Or perhaps, there was simply no more time left to buy?
On this day, June 22, 1941, Nazi Germany launched its invasion of the USSR, a military operation known as Barbarossa(Unternehmen Barbarossa). It was the largest military operation in the entire history of warfare.
The operation was named after Frederick Barbarossa (“Red Beard”), a German king from the 12th century.
This grandiose plan had several objectives. Firstly, to conquer the western part of the USSR and settle Germans there. Then, to turn the local population into slave labor. Another objective was to seize what Nazi Germany critically lacked and desperately needed to realize its ideological goals — oil from the Caucasus. Ultimately, the general goal was to create “living space” (Lebensraum) for Germany and to eliminate the Slavic people entirely — through mass deportation to Siberia or forced Germanization via enslavement and genocide.
Thus, the start of Operation Barbarossa was a fundamentally criminal act, pivotal in Hitler’s aspirations for global domination.
Germany was supported in the attack on the USSR by other Axis powers, and together they sent a total of 3.8 million soldiers into Soviet territory. The invasion began on this day along a 2,900-kilometer front, involving 600,000 motor vehicles and over 600,000 horses.
Let’s recall, World War II began on September 1, 1939, but this was a massive escalation — geographically, militarily, and politically — as the USSR now joined the anti-Hitler coalition alongside Western nations.
Operation Barbarossa opened the Eastern Front, the largest front in World War II. Some of the greatest battles in history would take place here, with enormous casualties for both Soviet forces and the Axis powers.
It’s no exaggeration to say that Operation Barbarossa, and everything that occurred on the Eastern Front, directly influenced not only the outcome of WWII but the course of human history.
Initially, Nazi forces were quite successful, capturing about 5 million soldiers from the Soviet Red Army.
The methods were brutal — it’s estimated that the Nazis starved or executed 3.3 million Soviet POWs, along with millions of civilians. Over 1 million Soviet Jews were also murdered as part of the Holocaust.
Despite this strong initial momentum, Operation Barbarossa ultimately failed. The German military did achieve some objectives, particularly seizing key economic areas in what is now Ukraine. However, by late 1941, their offensive began to slow, especially during the Battle of Moscow. This was followed by the first Soviet winter counteroffensive, which pushed the German army back by around 250 kilometers.
Furthermore, the Germans had expected the Red Army’s resistance to collapse in Poland — but that never happened. The Soviet army absorbed the initial shock and entered a war of attrition, for which Germany was unprepared.
Germany began running out of troops and could no longer launch wide-scale attacks. They were forced to focus on smaller operations.
The following year, they attempted to reach the rich oil fields of Baku, but had to pass through Stalingrad (now Volgograd). There, the stage was set for what most historians agree was the largest battle in human history — from August 23, 1942, to February 2, 1943, hundreds of thousands, possibly millions, died in and around Stalingrad. It was here that the German army broke, marking the beginning of the end not only for Germany’s campaign against the USSR but for Nazi Germany itself, which would later be destroyed by the Allies — although the Soviet Union unquestionably made the greatest contribution.
But let’s return from the end to the very beginning, to June 22, the launch of Operation Barbarossa. One major question still sparks debate today: Did Stalin know Hitler would attack? Or was he naive enough to believe in the non-aggression pact Germany and the USSR signed in August 1939 (the Molotov–Ribbentrop Pact)?
It’s not easy to answer this question, but first, let’s rule out the obvious — No, Stalin was certainly not so naive as to think the pact would protect the USSR from Hitler’s aggression. In fact, Stalin believed Hitler would attack, but he didn’t expect it to happen so soon — he hoped he had until 1942 or perhaps even 1943. But he knew the attack would come.
It is very likely Stalin agreed to the Molotov–Ribbentrop Pact to buy time. Of course, this doesn’t justify many of Stalin’s actions — especially since the pact included a secret clause dividing Eastern Europe between Germany and the USSR. But the pact must be viewed in the context of the time, and of the Soviet strategy to strengthen militarily, as they were very aware they couldn’t match Germany’s powerful Blitzkrieg war machine that had swallowed much of Europe.
Let’s remember the Winter War: the USSR failed to defeat even Finland (the war lasted from November 30, 1939, to March 13, 1940). This war exposed the USSR’s military weaknesses, especially to Germany.
Would Germany have attacked the USSR earlier had the pact not been signed? Possibly. Let’s recall that the pact was signed just a few months before the USSR–Finland war broke out.
Still, did Stalin know June 22, 1941, would be the date? Some sources suggest that the Soviet embassy in Berlin knew the exact date, but Stalin expected a different timeline — since May 1941, he was anticipating other potential attack dates. He still hoped Germany would seek some kind of truce or agreement with the West before starting a two-front war. In other words, he didn’t believe Hitler would risk fighting on two fronts.
Additionally, there was a flood of false intelligence circulating in those days — many reports suggested an impending German attack. It’s believed that Britain — under German pressure — hoped to provoke the Soviets into launching a preemptive strike, just to start the war between Germany and the USSR and relieve pressure on themselves.
Stalin certainly received intelligence indicating June 22 as the attack date. And yes, he didn’t take it seriously — not as a definite date — otherwise, the Soviet army would have been better prepared. But it’s important to understand that almost every day, new intelligence arrived with “a new attack date” — June 20, June 21, June 23, etc.
So, Stalin hoped he had more time — but he didn’t. Perhaps Hitler sensed Stalin’s mindset, and that’s precisely why Barbarossa was launched when it was — to achieve the element of surprise.
An interesting detail: right after the attack, propaganda posters began circulating in the USSR. One of them declared:
“The enemy’s foot has touched our great land. We shall crush these dark forces without mercy.”
Curiously, the posters did not mention who the “dark forces” were, nor was Germany visually represented. It wasn’t until three days later that more direct propaganda emerged, depicting Hitler as a rat, tearing up the non-aggression pact.
So, did Stalin know Germany would attack? He simply had to know. He was receiving daily intelligence since 1940warning of the attack. Germany had already violated all previous pacts and promises, further supporting the theory that an invasion was inevitable.
But did Stalin turn a blind eye to warnings that the attack would begin in summer 1941? Yes — perhaps because he simply didn’t want to face that reality, one that could have spelled defeat for the USSR. And he wouldn’t be the only one to “refuse to believe” such intelligence — ten years later, Truman and MacArthur ignored clear warnings that China had massed a million troops before Korea, leading to a disaster they could have avoided.
Similarly, Stalin wasn’t naive. The USSR was preparing for war, and Hitler knew that — which is why he rushed to strike first.
Interestingly, Operation Barbarossa was delayed by several weeks because Germany spent too much time conquering Yugoslavia. Germany attacked Yugoslavia on April 6, 1941, expecting a quick victory — but due to local resistance, Barbarossa was postponed, unintentionally giving Stalin a few extra weeks.
