What's going on in the rest of the world in lost memories (2009)?

[Terran Allias]

So I just found out about this Korean alt history movie where Japan still has claims in Korea. Here's a list of events on It's wikipedia page.

• 1909: An Jung-geun's assassination attempt against Itō Hirobumi is thwarted by a man named Inoue.
• 1910: The Empire of Japan annexes the Korean Peninsula.
• 1919: The March 1st Movement protests are suppressed with violence.
• 1921: Inoue, Itō's savior, becomes Chosen's (Korea's) second governor-general.
• 1932: The assassination of Yoshinori Shirakawa by Yoon Bong-Gil is prevented.
• 1936: The United States and the Empire of Japan enter World War II as allies against Nazi Germany.
• 1943: Japan takes control of Manchuria.
• 1945: Atomic bombs are dropped on Berlin, ending World War II.
• 1960: Japan becomes a permanent member of U.N. Security Council.
• 1965: Japan launches its first satellite, Sakura 1 (presumably as part of the Space Race).
• 1988: The 1988 Summer Olympics are held in Nagoya (in contrast to the city losing to Seoul in the actual timeline)
• 2002: The 2002 FIFA World Cup is held in Japan (instead of both South Korea and Japan)

All well and good but, what is going on in the rest of the world. For example the world map (which only highlights Japan) shows it has taken land from Russia.

Any idea, or speculation about the status of the worls outside Japan's borders.

I have never seen the film but my good guess is that Japan is able to keep much of its gains in Asia after WWI and then down the line, a KMT-ruled China becomes part of the Axis instead of Japan, of which prompts both Japan and the USA to unite; that and Japanese ultranationalist militarism being nipped in the bud sometime after the 1910's and before 1931.

As for Japan taking land from Russia, perhaps an Axis china captured that land from the Soviet Union, Japan took it from China and just never returned it?
