If you read the communications between Molotov and Ribbentrop, its clear the USSR didn't want to occupy their part of Poland (which btw were soviet lands stolen by Poland during the Civil War), but keep a rump Polish state there as a buffer state. However, what happened is the polish government escaped to Romania, and from there to the UK. The problem is that Romania was neutral, and thus, it couldn't allow the polish government, which was at war with Nazi Germany, to stay or pass through their country without them declaring war on Germany too. So the only way they could let the poles in their country was by interning them, meaning that they weren't a government anymore. Thus, legally speaking, the Polish State had ceased to exist. And since the Secret Protocol of the Molotov Ribbentrop Pact referred to Poland as "the Polish State", not "the Polish lands", this part of the pact was now invalid. And so the USSR had no choice but to occupy eastern Poland, since the alternative was to just let Nazi Germany occupy it and march right up to the Soviet border, which they could legally do without breaking the pact.nnThe whole thing was a legal mess, caused by the polish government cowardly fleeing and leaving their troops and people behind. If you want to read more on this I recommend the book "Blood Lies" by Grover Furr, which debunks many anti-Stalin myths including the Molotov Ribbentrop Pact.

And sorry to say, but, what other states did 100 years ago is totally relevant.

No I'm sorry, it's totally irrelevant. I have friends all over the world who hate the USA and its war in Ukraine. You takes on Russian people being crazy are immature and bigoted.

I despise any imperialistic, paranoid egomaniac where their ideals are more important than human lives. Hitler, Stalin, Putin, Trump, all are the same bullshit and as dangerous as the others. Any country trying to invade another is bad, no matter what.

Not a very nuanced take. I note that you don't have any American presidents in there or even, more relevantly to you, Stoltenberg.

This is US/NATO's war. They overthrew Ukraine's democracy and destroyed the country to try to "weaken Russia". They failed and Ukraine paid the price.
