Well... you're not supposed to begin thinking about the truth or the laws of physics. The symbolic and theologically significant number six was reached in a six day work week... that's all that matters.

People lie...  doesn't change the fact that they really do kill each other too, even if they lie about that too.  Side note, it's the sacred six million "Holocaust"/sacrifice that has been used to create the right of return.  So I wonder, what would Palestinian lies create... if they were better at lying?

Another side note... if America had lost the war and the Japanese owned and operated more media and printing presses then guess how their internment camps* might have been framed in the end.  It wouldn't change the fact that they had been victimized and discriminated against.  But people like to exaggerate...  and exaggerating or lying about history seems to be the keystone for victimization propaganda on all sides.

Anyway, the truth is that the Nazis adhered to a biological vision rooted in Darwinism so they didn't care if people happened to die in their racial struggle, etc.  But they didn't necessarily target and kill as many people as those interested in their sacred number of six million (a cabal's sacred number reported in some papers long before WWII) want to say either.

In any event, if you're interested in the truth then the laws of physics are usually a good place to start.

*Almost 120,000 Japanese Americans and resident Japanese aliens would eventually be removed from their homes and relocated.

About 2,200 Japanese living in South America (mostly in Peru) were transported to the United States and placed in internment camps.^[112]
Approximately 5,000 Germans living in several Latin American republics were also removed and transported to the United States and placed in internment camps.^[113] In addition at least 10,905 German Americans were held in more than 50 internment sites throughout the United States and Hawaii.  Wikipedia  (No word yet on whether or not this creates some type of "right of return" for all Japanese internment survivors and their descendants to a plot of land on the border of America and Mexico...  but hey, why not?  And if FEMA camps are ever used in America, it would seem that they'll create a new geopolitical situation somewhere hundreds of miles away too.)
