I'm getting Russo-Japanese vibes from this war.

Tsar Nicholas starts an imperial war of aggression with Japan to obtain a warm-water port, while the Japanese Navy (supplied with last-generation ships from the British Navy) surprises the world and proves to be able to fight the Russians on the world stage.

Turns out that those old British ships were still pretty good, and the Japanese have learned how to use Western guns and tactics by the early 1900s (despite being a Samurai/Sword society just 40 years prior).
