Encouraged by the imperialists of the West, in May 1939, Japanese militarists launched military operations against the Mongolian People's Republic in the area of the Khalkhin Gol River.
Having an agreement on mutual assistance with the MPR, the Soviet Union came to the aid of the Mongolian people. At the end of August, in decisive battles, the Soviet-Mongolian troops defeated the aggressor.
It was the defeat at Khalkhin Gol that played a major role in Japan's abandonment of plans for an attack on the USSR, even in 1941, which was difficult for us. This allowed the Soviet military leadership to transfer part of the Far Eastern divisions to the west, primarily to help defending Moscow.
After the defeat at Khalkhin Gol, Japan launched the tip of its aggression south and east against China, the USA, Great Britain, their allies and colonies. The Japanese invaders conducted offensive operations in a vast territory, which included a significant part of China, Burma (including military operations on the border with India), Vietnam, the Philippines, Indonesia, the northern regions of Australia and numerous Pacific islands belonging to the United States and Great Britain.
At the same time, the danger of Japan starting a war in the Soviet Far East remained until August 1945, but the lesson of defeat at Khalkhin-Gol was not in vain for the Japanese military.
