If Lenin decides to listen to Trotsky and Stalin and stop at the Curzon Line in 1920 instead of going for Warsaw, and if the Bolsheviks are able to repulse any renewed Polish attempts to expand east of the Curzon Line (thus getting the Poles to agree to the Curzon Line as the Soviet-Polish border), where do the Bolsheviks go from there?
Specifically, do the Bolsheviks decide to immediately try grabbing any additional territory--such as Finland, the Baltic countries, Subcarpathian Ruthenia, Bessarabia, and northern Bukovina?
Also, with a Polish-Soviet border on the Curzon Line, does Poland become more receptive to Nazi overtures for an alliance in the late 1930s?
In addition, if the Soviet Union has a common border with Czechoslovakia in this TL, do Britain and France decide to fight on Czechoslovakia's behalf in 1938 in this TL?
Thoughts?
