They didn’t, they prevented the attacker from taking all of Poland. The goal of Nazi invasion was to grab land and labor, to colonize Poland, not to just attack Poland. Preventing more people from being colonized by the genocidal Nazis is a good thing.
The Nazis would have taken all of Poland had the Soviets not forced them to honor the non-aggression pact, and Britain and France were doing jack-shit other than a naval blockade. You’re either saying the Soviet Union should have attacked Nazi Germany there and then when they were weaker than Germany and had no alliances, or that the Soviet Union should have left Poland to the Nazis. The former is horrible strategy, the latter is holocaust trivialization.
I’m just saying they both did invade, Nazis first and then USSR joined in invading Poland later. I’m just trying to find the agreement on even this basic fact.
The Soviets went in after the Polish government collapsed and the Nazis had already taken Poland, in order to prevent the Nazis from advancing further. The Soviets were not interested in conquest or land-grabbing.
Nazis hadn’t taken all of Poland, just parts of it. In the end both got the parts of Poland they had agreed upon (with the Lithuania thing affecting it too).
“Well we tried to form a formal alliance but you didn’t agree to it, so that means we’ll join your attacker.”

The Soviets didn’t “join the Nazis.” After Poland fell, the Soviets went in to prevent the Nazis from colonizing all of Poland.
Nazis were invading Poland from the West and USSR joined them later by invading from the East. It’s pretty cut and dry.
