If you want to refute my points you are welcome but, please, be factual.
Just to say BS is not enough, especially when we are talking about propaganda.
Russia was out of war early, because Lenin was a German spy. That was the entire point of the Communist revolution and why the German intelligence paid for it.
Lenin surrendered on the Eastern front as part of the deal and gave up on Western parts of Russian Empire.
Germany later planned to gobble it for itself but the Western allies prevailed.
Poland, being itself a part of these released Russian territories, decided to improve its standing by establishing the Empire of its own. They acted like opportunists exploiting the vaccum of power and turmoil.
Bolsheviks managed to get back most of it in a couple years and that is largely because the treatment of the locals by the Polish was dismal.
In fact in 1939 Stalin took back the rest of the lands annexed by Poland at the end of WWII.
It was somewhat pitiful for modern Ukraine because exactly these territories made it into a Third World country nowadays.
Calling Lenin a German spy might be a bit of a stretch but he was definitely supported by the Germans. They bought him a printing press to use in Petrograd.
After Brest Litovsk the Bolsheviks were threatened from all sides but it was uncoordinated. By the end in 1920 the Baltic states and Besserabia were free as were lots of country formed from the Austrian empire. Interestingly every new country including Germany started territory fights on their borders. Everyone wanted to revive their old empires which is why it is called the Blodlands.
In 1940 while the Germans were smashing France, which was suppose to turn into another ww1, the Soviets took the Baltic states and Besserabia/Moldava. Given this put Ploesti a 2 days march by tanks from the new border and given 60+% of German oil came from there Hitler started planning Barbarossa.
