The Holocaust, despite retroactively considered to have lasted from 1933 until 1945, should really be considered to have started only in 1941 when the meaning of "Final Solution" is argued to have changed from liquidation (i.e. expulsion to the marshy parts of Russia, as Hitler put it) to innocenticide, as 1941 is argued to be the first year that gas chambers went operational.

Concentration camps that allegedly had these gas chambers were, in the beginning, all camps; after international investigation on the American-liberated camps, all the testimonies making the case that there were gas chambers in those camps were pushed aside, and it was revealed that they were all fantasies. Indeed, today it is accepted that there were no gas chambers in any American-liberated concentration camp, despite detailed descriptions of their operations, including trapdoor floors that would fling open to dispose of the bodies, not to mention other fantastical methods of human disposal (electrified floors, pedal-powered killing machines, etc) that despite all credible testimony, turned out to be false.

In the end, only those camps that were liberated and immediately destroyed and rebuilt by the Soviets, are today said to have had gas chambers. The evidence, however, once taken out of its political context, is scarce. Historians and researchers that have attempted to find out the details of the procedures of those methods of killing involving gas chambers have perforce arrived at much lower numbers of estimated deaths due to constraints that only become apparent once one is forced to think of all the logistics involved in such an underfunded operation that could be readily exposed by the Red Cross who was in every camp and given free reign to come and go, and whose communications with the outside world were not intercepted nor subject to vetting prior to transmission.

Auschwitz is the best example of ongoing research on the face of political resistance. Its death toll has plummeted from 4 million to as low as the official reports by the Red Cross which despite seeming incredibly low, nonetheless are time and again confirmed against independent measurements and estimates (like the communication between camps and their leadership which was intercepted by the British and released to the public much after the war and the subsequent show trials. Another example of ongoing research into Auschwitz is that the room that is now shown to be a gas chamber in the Auschwitz Museum, was actually uncovered to be a Soviet reconstruction, as admitted by then head of the museum, in an investigative piece of journalism by Jewish researcher David Cole.

Nowadays, despite immense political censorship and general public ignorance due to several reasons, including media influence, Jewish emancipation, public inertia and confirmation bias, and so on, research continues. At the forefront of this research it is possible to find evidence that during Jewish liquidation (i.e. expulsion) some might have been chaperoned by Soviets once far enough East, and then sent to Siberia where they were slaughtered. There still remains details to be accounted for. Throughout these years since the Holocaust, several archives opened up, in a piecemeal fashion, all the way into the 1990s and a bit beyond. Every time one archive openings were announced, most historians would anticipate that better, more direct evidence for the existence and operation of gas chambers would finally surface and vindicate their pre-conceived conclusions. And every single time after the opening and visitations by the most illustrious of historians, they would come out empty-handed, disappointed that the newly available evidence could not be used to resuscitate the notion that gas chambers were used to commit innocenticide. Hence the need to rely on numerous movie releases and museums across the world to spread the message, as it is not a scientific message that can be passed from one person to another with "just the fact, ma'am" and none of the narrative that presupposes the facts. If you care to get your feet wet and plunge into this research yourself, look no further than Raul Hilberg on video admitting that he never vetted the estimated number of deaths from gas chambers, instead relying on the numbers that he heard during his own education and elevating those numbers to official status with the seal of approval that his name imparts. Indeed, not much of the whole mainstream Holocaust narrative can stand alone if stripped of its defenders, the personalities that give color to this story. In this sense, it is like Psychoanalysis in that a group of people with preconceived ideas of a narrative will shun outsiders and dissenters and shame them while upholding an illusory moral ground supported by the ideas and agenda of a radical group of influential thinkers who will stop at nothing to "better the world" through any means necessary.
