In the European theater of World War II, if there was any country with the most serious losses, it was the Soviet Union, which fought against the German army on the Eastern Front. Due to the strength of the German army and Germany's understanding of the Soviet Union before the war, after the outbreak of the Soviet-German War, the Soviet Union was once advanced by the German army to the capital. In this war that lasted for several years, the Soviet Union lost more than 20 million people.
The losses were already so heavy, why did the Soviet Union, which had just taken control of the Soviet-German war, not concentrate all its forces to counterattack Germany, but immediately swing the butcher knife at "its own people"? You know, it was not a group of people who were liquidated by the Soviet Union in World War II, but three entire Soviet nationalities.
What did these people do to make the Soviet Union prefer to have a blood feud with Germany than to act against them eagerly? When it comes to war, what people hate most is not the invaders, but the "traitors" who turn to the invaders and wield butcher knives at their own countries. And these three peoples made this mistake and became the "intelligence providers" and "vanguards" of the German invasion of the Soviet Union.
Why did the three peoples betray in the war and help Germany destroy the Soviet Union? This also starts with the Soviet Union's previous Tsarist Russia. In the years of conquest, Tsarist Russia occupied a large amount of land and absorbed many nationalities, making Tsarist Russia a multi-ethnic country.
The Soviet Union, established after the revolution, not only inherited everything from Tsarist Russia, but even surpassed Tsarist Russia's territory for a time. The pre-war Soviet Union was in the midst of Stalin's reign, and the "Great Russianism" of this period made the rest of the Soviet Union very oppressive, believing that their nation was oppressed to the extreme. The Soviet-German War broke out shortly thereafter, and these peoples thought their "opportunity" had come.
One of these ethnic groups is the Chechens. Although Tsarist Russia occupied the Caucasus by war two centuries ago, turning the Chechens into their own subjects, some Chechens fought against Russian rule from time to time. After the overthrow of Tsarist Russia, the Chechens established the Chechen Autonomous Republic, which belonged to the Russian Federation and naturally became a subject of the Soviet Union.
After the outbreak of the Soviet-German war, the Chechen elite intended to rely on German power for independence, so they provided a lot of Soviet intelligence for the German invasion. At the same time, some radical Chechens joined Germany directly, brandishing butcher knives at the Soviets.
After the Soviet Union determined the superiority of the Soviet-German war situation, the Soviet Union did not put all its forces into the German battlefield, but on the grounds of "Chechen betrayal", dispatched hundreds of thousands of troops and thousands of armored vehicles, and exiled more than 400,000 Chechens to remote areas in Central Asia. In the process of exile, tens of thousands of Chechens died on the road because of hunger and disease.
The other was the Crimean Tatars, a people similar to the Chechens, who also defected to Germany during the war. At the time of the Soviet liquidation, it was discovered that this nation hid a large number of weapons and equipment, far from being able to be completed by a small number of people, so the Soviet Union considered the Tatars to be a betrayal of the whole. Subsequently, the Soviet Union sent troops to expel the Tatars from the territory of present-day Uzbekistan, leaving the Crimea region basically free of Tatars.
The last one is the Kalmyk Mongols. Although the nation was allowed to establish its own autonomous republic for its support for the October Revolution, in fact it was not only subject to direct control by the Soviet Union, but also deprived by the Soviet Union of the right to keep horses. When the Germans invaded, some of the Kalmyk Mongols chose to betray. This betrayal also led to the exile of all the people of this nation to Siberia.
