A quick snapshot of the World in January 1933:

Mao Zedong is sitting in Yan'an, busy fighting Chiang Kai Shek 's Nationalist warlords from the outside, and busy purging the supporters of the Moscow trained "28-Bolsheviks" within the party. Despite some superficial similarities between the land redistribution policies of the CPC in Yan'an and Moscow's agricultural policies, he has being secretly reading a translation of the works of Leon Trotsky. However, he cannot quite be so open about this until he finds some way to purge Soviet "agricultural adviser" and Comintern agent Nikolai Yezhov [1], whom Mao suspects was sent by Moscow to keep an eye on him.

Walter Ulbricht is in Paris, having fled under an assumed name after the recent Nazi victory led by Adolf Hitler, in battle for Germany. Despite a half-hearted alliance with the Social Democrats [2], the Steel Helmets and the Red Front couldn't keep the Nazis at bay. Oh well....he will soon be heading to Hotel Lux in Moscow to wait another shot at the revolution. While at a Parisian Cafe, he had a very interesting chat with an idealistic young Briton named Kim Philby.

Franklin Roosevelt has defeated incumbent Republican Herbert Hoover, and is preparing for his inauguration and a "New Deal" for America...

Heinz Guderian is giving a lecture on logistics at the Frunze academy in Moscow [3], which is attended by deputy defense Comissar Mikhail Tukhachevsky, at the reception the two agreed that the new German government is likely to recall German military missions in the Soviet Union. And bid each other farewell with some regret.

[1] Funnily enough, Yezhov was deputy commissar for agriculture in the late 20s otl. In atl, he lost some power struggle in the post-Stalin era and has being sent on what is effectively an exile to China.

[2] The Comintern doesn't take the "Social Fascist" line ttl, but the KPD itself was pretty dubious about cooperating with the SDP

[3] German officers did do this during the Interbellum due to the Rapello Pact

Overall, the world has not changed too much from OTL. The butterflies thus far have being contained to the USSR and the global Communist parties.
