In Götz Aly's book '''Final Solution': Nazi Population Policy and the Murder of the European Jews'', Aly points to a very specific proposal by
Rolf-Heinz Höppner, who at the time was simply an
SS-Obersturmbannführer (or an SS Officer). This letter written by Höppner was sent to
Adolf Eichmann about a viable solution to solve the
Jewish question. In a portion of the letter he wrote: There is a danger that, in the coming winter, it will become impossible to feed all the Jews. It must seriously be considered whether the most humane solution is to finish off the Jews unfit for labour through some fast-acting means. This would definitely be more pleasant than letting them starve to death. The letter, which was sent on July 16, 1941, is one that functionalists arguing the bottom-up approach utilize as evidence. Aly goes deeper and explains that the letter had not only been written by Höppner, but it had also been discussed at a lower level. Götz Aly writes, "Thus it was the lowest ranks of the resettlement apparatus that thought up 'things' which, it was said, 'sometimes [sounded] fantastic'." Aly is not the only one that argues that the lower ranks were responsible for bringing about The Final Solution—though he is the most recognized.
Dan Stone, author of the book
Histories of the Holocaust, asserts that "The perpetrators on the ground were not automatons who simply followed instructions from Berlin; they were much worse—active agents who drove the murder process forward at every stage." However, he is less extreme than Götz Aly since he gives the leadership credit for making the process a reality. Stone cites the work of the
Einsatzgruppen in the months leading up to the decision to exterminate the Jews. As
Timothy D. Snyder, author of the somewhat controversial book
Bloodlands: Europe Between Hitler and Stalin, describes the situation, Einsatzgruppen were being used as a way to tally up mass shootings of Jews to report back to
Reichsführer-SS Heinrich Himmler as a method to continue rising in ranks. ==Competing approaches==
