I don't know how accurate is what you explain, but the fact that Eichmann was not tried at Nuremberg certainly does not help your credibility.
Looks like it was the Israelis who put him on trial:
https://en.wikipedia.org/wiki/Eichmann_trial
> When he took the stand in his own defense, he portrayed himself as a mid-level functionary following orders.[32] He repeatedly claimed he was "merely a little cog in the machinery" of genocide, not a policymaker.
Eichmann escaped from custody in 1945 and successfully hid until Mossad tracked him down in Argentina in 1960.
