SOVIETS, JAPANESE CLASH AT KHALKHYN GOL

Tokyo, Japan · May 11, 1939

Europe, the United States, and Japan, profiting from the techno­logi­cal, eco­no­mic, social, and mili­tary advan­tages con­ferred on their coun­tries by the Indus­trial Revo­lu­tion, began placing weaker nations else­where in the world under their “pro­tec­tion.” The United States did that in 1898 when the Philip­pines became an Amer­i­can terri­tory. Japan declared Korea, lying across the Sea of Japan, a protec­tor­ate in 1905 and five years later annexed the coun­try (see map below).

Japa­nese mili­tarism and aggres­sive trade poli­cies on the Chin­ese main­land in the early twen­tieth century led Japan to gar­ri­son “ad­visors” there in the 1920s. Japa­nese troops based at Muk­den (today’s Shen­yang) in North­ern China staged a bomb attack (allegedly by Chinese dissi­dents) on a Japanese-owned rail­road. The “Muk­den Inci­dent” of Sep­tem­ber 18, 1931, was the ruse for seizing the pro­vince of Man­chu­ria, which bordered Korea on the east and, on the west, Outer Mon­go­lia, a de facto pup­pet state of the Soviet Union. The Japa­nese crea­tion of Man­chu­kuo became the launch pad for more Japa­nese land grabs in the 1930s.

On this date in 1939 a fierce unde­clared war on the Mon­go­lian plains broke out between Japa­nese forces from Man­chu­kuo and Red Army forces sta­tioned in Outer Mon­go­lia. Although the Battle of Khal­khyn Gol (May 11 to Sep­tem­ber 16, 1939) is little-known in the West, it had pro­found impli­ca­tions on the con­duct of World War II in Asia and Europe. Khal­khyn Gol may be said to be the first deci­sive battle of the Second World War: it deter­mined that Japan and Ger­many, the two prin­ciple Axis powers bound to­geth­er in a full-blooded mili­tary alli­ance (the Tri­par­tite Treaty signed in Berlin on Sep­tem­ber 22, 1940), would never geo­graph­ically link up their areas of con­trol through the Soviet Union.

Japan’s defeat at the Battle of Khal­khyn Gol con­vinced the Impe­ri­al Gene­ral Staff, which held a strangle­hold over suc­ces­sive Japa­nese civil­ian govern­ments, that seizing Soviet resources in Northeast Asia was not ten­able. Instead, the rich resources of South­east Asia, espe­cially the petro­leum- and mine­ral-rich Dutch East Indies (today’s Indo­ne­sia), looked more and more appealing, leading directly to the attack on the Philip­pines, the Dutch East Indies, Brit­ish Malaya, and the Amer­i­can possession of Hawaii on December 7 and 8, 1941.

After the occu­pa­tion of Korea (1905) and Man­chu­ria (1931), Japan’s mili­tary leaders in China focused expan­sionist aims on Soviet terri­tories in North­east Asia, and con­flicts occurred fre­quently on the Man­chu­rian border, in fact as early as mid-1929. The army’s aggres­sive plans somet­imes caught the civil­ian govern­ment in Tokyo by sur­prise, as the 1931 “Muk­den Inci­dent” (also known as the “Man­chu­rian Incident”) showed.

The rapid defeat of Japan’s Kwan­tung Army, as its army in Man­chu­kuo was called, was a signi­fi­cant factor in Japan’s sur­ren­der. Japa­nese leaders ima­gined the Red Army as poised to invade the Home Islands with boots on the ground, while the Amer­i­cans were viewed as per­fectly con­tent to incin­erate the Home Islands using their fleet of heavy bombers.
