I mean, the obvious answer is instead of trying to divvy the sovereign nation between them, they should have stood up for them and defended them when the Nazis rolled in. Barring that, they should have liberated them, then left them the fuck alone. Even a stopped clock is right sometimes, this comparison is pretty clearly silly. They weren't lamenting the lives of Nazis lost in the battle to push them out of Poland. They were lamenting the lives of the Poles after falling under the Russian boot, after the battles were won.
