it’s clear they wanted to keep him [Hitler] on a leash and have him serve as a first line of defense
This is basically the thing I’m arguing. The Soviet Union was never an expansionist project in the military sense (they wanted to spread the revolution abroad, such as by assisting the Republicans in Spain and giving weapons to the Vietnamese in their anti-imperialist struggle), never projecting their military force outwards except as a response to serious provoking by third party foreign actors (such as in the case of the funding and arming in Afghanistan of radical theocratic militias by the US).
The fact that all of these western leaders talk of the USSR using the Molotov-Ribbentrop as an “odious but necessary defensive measure”, proves to me that they understood that the USSR wasn’t something they needed to be militarily defended of by a weaponized Germany acting as a buffer, hence that can’t be understood as Germany’s role in the situation in my opinion.
Good, then we both agree the source doesn’t support the “hundreds of thousands murdered in Poland” claim.
For the last time: I have asked at this point in 4 different occasions what was the desirable alternative to a Soviet military occupation of eastern Poland after the Polish, English and French rejection of a mutual defense agreement with the USSR.
The fact that you fail to provide an answer after being clearly prompted 4 different times to give one, is enough evidence to me that you simply don’t have one. I will then state the obvious: the Soviet military occupation of Eastern Poland likely prevented hundreds of thousands of Jews, Poles, Roma and other ethnicities from being genocided by the OTHERWISE INEVITABLE Nazi invasion.
No, I really cannot pretend knowing more about defeating fascism in Europe that the nation which ultimately defeated fascism, at the IMMENSE cost of 25 million lives in the struggle against Nazism. It’s easy to go with our hindsight and categorise the oppression of bourgeois and nationalist elements of Poland as unnecessary and “barbaric”. But you known what, I’m not Polish, I’m Spanish. I’m from the country where the communists did not go far enough, and the result was losing a preventable civil war against fascists which murdered hundreds of thousands of innocents, and the 4 decades of fascism that followed. So, no, my claim is NOT that I know more about fighting fascism than those who actually defeated it.
