If you're referring to the first time eastern forces defeating western forces since the beginning of the use of firearms, the credit should go all the way back to the Ming Dynasty forces defeating that of Portuguese and Dutch on China's shores and the Taiwan island.
No Comparability at all Between Rus-Jap war and Sino-US war
The Rus-Jap war of 1904 was fought between two running dogs of the Western Dominance club over robbing a piece meat from the Sick-man China. Both Tsar Russia and Imperial Japan were later-comers to the Western colonist feast that had been going on since 1492. Both were small powers in the Western Dominance club. And both were treated as inferiors by elite Western dominant powers. Tsar Russia was looked down by its Caucasian cousins due to its backward industrialization and poor social development. Imperial Japan was treated as a second class inside the Western Dominance club due to, besides its relatively backward industrialization, its unfavorable racial profile. Western elite powers ranked them both as coffee boys, not equal members.
What fuss could two coffee boys' fight stir up in the house of an elite club? A storm inside a coffee pot to say the most. Their social status determined the maximal potential of the coffee boy fight. The Rus-Jap war of 1904 is so trivia that left almost no mark in world history. It has no comparability at all to the Sino-America war of the 1950s.
Unlike the Rus-Jap war of 1904, the Sino-America war of the 1950s fundamentally overturned the status quo of the past 500 years since 1492. From Christopher Columbus' discovery of the New Continent in 1492 to the start of the Korean War in 1950, the Western way of dominating the world had been the military power play. That is, coming to the doorstep of other countries, using advanced military hardware to subdue local residents, and enslaving them. This Western military power play of 500 years has never failed, and has been the kingpin of Western dominance to conquer the world. But this Western military power play suddenly came to its end when an agricultural China with backward military hardware defeated, MILITARILY, the best army of King World in battle fields in Korea. This event has changed the development course of the world from then on. And the world is no longer the same in the eyes of both Westerners and non-Westerners.
If there is anything that makes the Rus-Jap war of 1904 commendable today, that is the ugly inflation of Japanese ego after it became a junior member of the Western Dominance club. Japan used its unhappy experience in the Western club as an excuse to justify its aggression in Asia and its win in the Rus-Jap war of 1904 further intensified the Japanese ego inflation. Under the influence of an inflated ego, Japan robbed its neighbors of their properties, burned down its friends' houses, raided its teacher's home, raped its friend's daughters and wives, slaughtered its neighbors' families,... It committed terrible anti-human war crimes all over the Asia-Pacific and bred a variant of secondary class Japanese toads in Taiwan.
Today, when you see an Asian of non-Japanese origin glorify Imperial Japan, the chances are, nine out of ten, you've entered a Taiwanese Green Toad, aka a spiritual Japanese. Never waste you time and energy on trying to educate a spiritual Jap. Being somebody else spiritually, a Taiwan Green Toad is, nine out of ten, below the level of educable. The only proper way to educate the Taiwan Green Toads is, choosing a sunny day after China eliminates absolute poverty in 2021, to wipe all of them into the Pacific, let them choose among swimming to their colonial breeder of Japan, or swimming to their new master Uncle Sam, or swimming back to the Chinese territory of Taiwan. They'll have to learn how to save themselves in front life and death reality.
