The Soviets had no intention to get common borders with Nazis.
But they had every intention of subduing Poland, they'd enter with their armies and duke it out here.
wanted the states between them and Germany to work as a buffer to keep the german forces away.They would just keep bases without changing the government in Poland.Soviets wanted to have bases in Finland,Hungary,Poland,Romania and even Denmark.
Oh please Southern, a country that repeatedly stated that Poland needs to go would just keep bases? Is that some cheap provocation or dont you know your history, 19 years before they tried to wipe us out and you're expecting people to buy that?
Polish goverment didnt buy it then (quite correctly) and its hardly a mistake.
Chose to fight with no perspectives and no help from the West for a lost cause.
But we chose to fight
instead of just bending over and watching our women raped, economy plundered and elites murdered, that was the Russian intention all along, it would happen anyway, the only thing we could keep at that point was our pride.
Why towards Germany?Most probably they would ally with Poland,Czechoslovakia against Germany.
Mainly because RUssia caused the great hunger and Germany was another anti-Polish state with power, no one gave a dime about Czechoslovakia back then since it was outside the main game.
Czechoslovakia refused to fight.
Again your lack of historical knowledge, Czechoslovakia was willing to go to great lenghts to achieve a compromise with Poland, with a huge Polish army backing them they were most definitely willing to fight and given their level of motorisation and strategic positioning together we would have a good shot at Germany, maybe not conquering it but definitely breaking its military.
