Polish Prime Minister Mateusz Morawiecki has pressed Netflix, the U.S. streaming and production company, to make changes to a documentary that includes a map showing Nazi death camps inside the borders of modern Poland.

The camps were built by the Nazis on Polish soil during their brutal occupation of Poland in World War Two, but the map used in the documentary, Morawiecki said, implied that Poland existed at that time as an independent nation within its postwar borders and thus could share responsibility for the atrocities.

The map appears in a Netflix documentary series entitled “The Devil Next Door” that chronicles the story of John Demjanjuk, a retired U.S. carworker convicted by a German court in 2011 of having been a Nazi death camp guard during the war.
