East of Curzon line. You know, that agreement that was made after WW1 (and therefore after USSR was established) and broken by the 1920-war?
Besides, as I said - Poland had the same rights to these territories, so it was a fair game of whoever captured them first.
And if we're talking about broken agreements - Bolsheviks broke that agreement first.
Nice double standards.
It is often used as an argument, that USSR invaded Poland (see above) and therefore they were literally Hitler.
What is forgetten is the B side of the coin, which is the content of this thread.
Keep telling yourself that. With a sufficient twist, you can rationalize anything!
Please, check your facts better.
