meanwhile France and UK simply sat on their asses against empty unguarded border

nobody cared about the poles

Yes, and actual history yet again subverts the dominant story:

> The citizens of Poland have the highest count of individuals who have been recognized by Yad Vashem as the Polish Righteous Among the Nations, for saving Jews from extermination during the Holocaust in World War II. There are 7,232 (as of 1 January 2022) Polish men and women conferred with the honor, over a quarter of the 28,486 recognized by Yad Vashem in total. The list of Righteous Among the Nations is not comprehensive and it is estimated that hundreds of thousands of Poles concealed and aided tens of thousands of their Polish-Jewish neighbors. Many of these initiatives were carried out by individuals, but there also existed organized networks of Polish resistance which were dedicated to aiding Jews – most notably, the Żegota organization.

As a Pole, I am pissed af about the fact that this true story of WWII is not known. In fact, very often the Russian version of "pravda" is what has been spread.

Why tf is there no Oscar winning movie about this story?

Poland is invaded from both sides, saves the most lives of our fellow Jewish brothers and sisters: the most heroic story, and the movie count is zero.
