A truly moral Nuremberg Trial would have considered the war conduct of the Allied and Neutrals, as well as that of the Axis...
(Cite here the Holocaust, Aktion T4 and the Hunger Plan.)
Eugenic Triages from all sides of WWII
Naval blockades, aerial bombings and denying the spreading of information about new life-saving medicines and pesticides were the ways the Allied hoped to avoid engaging their 1A young males in hand to hand combat with 1A males from Germany, Japan and Italy.
The British scientists and the military had been united as one with British politicians is disclaiming any need for British troops to invade Germany to fight German troops there.
European part of that war, that British 1A males finally engaged in deadly combat with 1A German males on German soil.
(The whole war might have ended in months not years, if only the vastly larger manpower pool of the French and English empires had been conscripted into a ground army intent on invading western Germany while the bulk of her army was in the East , invading Poland.)
Instead, they said, naval blockades and aerial bombings and denying new lifesaving medicine would kill enough women, children and elderly in Occupied Europe and Germany to make the young male German 1As want to voluntarily surrender, far in advance of any British invasion with ground troops upon German soil.
Of course, the Neutrals did the best eugenic job of the lot in preserving their own 1As and not diluting them with any 4F gene pools.
They did so by (A) not joining the effort to defend the weak and the small and the innocent and by (b) not letting any of the weak/small/innocent into their countries as hapless refugees.
The dysgenic myth of WWI
It was claimed by avid eugenists during WWI (and by most educated people after the war ) that only the best had died in the Great War while back home the cripples and mentally deficient had breed like rabbits.
No evidence was put forth to support either of these claims - it seemed so common sensical.
In fact by the end of it, the Great War had killed millions of men who either had been or would have been rejected as 4F material at the start of the war - a war this big cut a wide swath through all men with two legs, from 18 to 45 , in most combat nations.
And the evidence shows in fact that the physically and mentally challenged people around the world and through all the ages marry less frequently and have kids less frequently than the average population.
It is pretty hard to marry and raise a family without first having a steady well paying job - as most of us who are physically and mentally fit already know first hand.
How much harder for those with mental or physical challenges ?
So, absorbing this false lesson , all the post WWI world's elites sought to avoid wars where their 'best' took on the 'best' from a nation of equal or greater demographic and military power.
This didn't mean no more war - it just meant that post WWI nations tended to attack nations smaller than themselves or to invade countries bigger than themselves that they thought were divided internally or were inept as warriors.
So Germany and Japan invaded Russia and China under reason one, while Japan attacked America under reason two.
And in any and all cases, nations tried to first win wars by killing or terrifying or starving/freezing the civilians of an opposing nation of a size similar to their own, rather than in engaging in direct combat with that nation's armed forces.
But because eugenics was invented in the victorious Allies's nations and only later taken up by the Axis and Neutrals, anything vaguely universally eugenic about the whole war was strictly excluded from consideration at Nuremberg - only crimes unique to the Axis were considered crimes against humanity.
Trust me on this one, every school child one hundred years from now will know WWII to be an eugenic war from push to finish - and on all sides ....
