Hey, no worry, I'd much rather get this game on the proper road again than hog my precious loose-end-tying.
Anyway.
ASIA
Following several Kuomintang/Communist incidents, Hitler is forced to denounce his support of the KMT to salvage his alliance with Moscow. He nonetheless secretly sends off several officers and weapons to China, under the cover of a purge. Stalin remains unaware, or chose to ignore this.
The western powers, however, do not ignore the incidents (and Japan and England takes a dim view on the sudden appearance of "exiled" german officers among the KMT forces). In August '27, England and Japan occupy Shanghai, with carrier support from HMS Eagle and Hosho. As most of the other western powers were concerned with the events in China and the threat to their concessions (indeed most quietly increased troop presence in their own concessions, even America), they stay silent. Further attempts to retake Shanghai lead to little; the anglo-japanese remains there.
The stalemate in Indochina continues. England and Japan quietly agree to provide France such naval support as she needs.
Late in 1928, Hirohito is crowned as Emperor of Japan.
EUROPE
Benito Mussolini makes a State Visit to Paris just in time to see Charles Lindbergh arrives. In Paris, he meet french politicians and american envoys. Over the next few months, resolutely free market isolationist America, France (scared into electing a rare stable right wing government by the German-Soviet alliance), and Fascist Italy arrives at a treaty whereby they agree to collaborate in intelligence gathering and police activities meant to contain the spread of communism.
Although England and Japan, due to hostility with the United States, do not formally join, they begin quietly collaborating with France and Italy all the same.
Informed of this development, Hitler is said to have laughed in childish delight at the news for several hours.
AMERICA
The United States spend most of 1927 troubled by the Catholic rebellion against the anti-clerical constitution of 1917. The revolt dies down slowly . As 1927 grows into 1928, the rebellion die down, and America enters an election year. The Election proves an easy victory for Republican Herbert Hoover.
MEANWHILE (all historical stuff!)
Trotsky is kicked out of Russia, the Australian parliament has a first meeting, Saudi Arabia becomes independant, the Academy of Motion Pictures is founded, Mickey Mouse is created, Elliot Ness begin cleaning Chicago, and the changeover from silent to talking movies occurs.
At the end of 1928, thus...
Alliances
Anglo-Japanese Alliance : British Empires, Japan, the Dominions (Canada, Australia, New Zaland, South Africa).
Treaty of Mutual Collaboration against Communist Infiltration (Rome-Paris-Washington Axis) : Italy, France, United States.
The Molotov-Ribbentrop Pact : Germany, Soviet Union (Hitler at least planning to turn Stalin into a Commie-Kebab as soon as he can)
Wars
Chinese Civil War : Kuomintang (backed in secret by Germany) vs People's Liberation Army (backed in secret by the Soviet Union)
Indochinese Rebellion : Vietnam rebels vs France (with limited naval support from England and Japan)
Other Conflicts
Shanghai Situation : Kuomintang (no backing) vs Anglo-Japanese alliance. No actual fightin, but high tension.
Even if the odds of success is low, us poles would revolt anyway
