Israel made public on Wednesday a decades-old handwritten plea from Nazi war criminal Adolf Eichmann for clemency for his role in the Holocaust, dated just two days before he was executed.
In the request, written after he was brought to Israel in 1960, then tried, convicted and sentenced to death, Eichmann claimed the Israeli court overstated his role in organizing the logistics of Adolf Hitler's genocidal "Final Solution" which involved the extermination of six million Jews.
Israeli President Reuven Rivlin presented the previously unreleased letter, which was written to then president Yitzhak Ben-Zvi, at a ceremony to mark International Holocaust Remembrance Day.
"There is a need to draw a line between the leaders responsible and the people like me forced to serve as mere instruments in the hands of the leaders," the presidency quoted Eichmann's letter as saying.
"I was not a responsible leader, and as such do not feel myself guilty," the Nazi wrote. "I am not able to recognize the court's ruling as just, and I ask, Your Honor Mr President, to exercise your right to grant pardons, and order that the death penalty not be carried out."
The letter was signed and dated: "Adolf Eichmann Jerusalem, May 29, 1962."
He was hanged around midnight on May 31.
It was the only time Israel used its death penalty; a bill last July to apply the death penalty to terrorists was shot down by the Knesset 94-6, with only the Yisrael Beytenu party that proposed it voting in favor.
Eichmann, one of the main organizers of the Holocaust, escaped from a prisoner-of-war camp after World War II and fled to Argentina in 1950, where he lived under a pseudonym until he was snatched by Mossad agents in Buenos Aires in May 1960 and smuggled to Israel.
The ability of the security services to bring him to justice was a source of pride for the Jewish state, and Rivlin referred to the trial as a momentous moment in Israel's history.
"In the first years after the Holocaust, the people in Israel were busy rebuilding and founding an independent state," he said. "The renewed Israeli society was not in the mindset to or able to remember."
"The Eichmann trial broke the dam of silence. The ability of the young Jewish state to capture the Nazi murderer afforded a basic sense of security to the survivors of the Holocaust."
Israel and its allies have continued to use their resources across the globe to pursue those responsible for carrying out the Holocaust, even though the majority of perpetrators are now close to death.
On Tuesday, the Simon Wiesenthal Center - named after a famous Nazi hunter - produced a list of 10 alleged Nazis who could be prosecuted in 2016.
Of the 10, four have trial dates already slated in Germany this year.
Efraim Zuroff, director of the center, said they would continue to chase every remaining perpetrator as "we owe it to the victims."
"The passage of time in no way diminishes the guilt of the killers. Old age should not afford protection to people that committed such heinous crimes," he told AFP.
"The trials send a powerful message about the significance of the Holocaust."
As the number of World War Two Nazis alive diminishes, Zuroff said they are also seeking to focus on historical accuracy - with strands of different societies in Europe keen to play down their role in the killings.
Israeli Prime Minister Benjamin Netanyahu, in a statement on Tuesday, warned that anti-Semitism was again growing in Europe.
"Even respected Western opinion leaders have become afflicted with hatred for the Jewish people and the Jewish state," Netanyahu said, without specifying names.
"The obsession with the Jews - the fixation on the Jewish state - defies any other rational explanation."
Other documents presented at Wednesday's commemoration, in the presence of Holocaust survivors, included requests for clemency from Eichmann's wife Vera and his five brothers, along with Ben-Zvi's letter to his justice minister rejecting the appeals.
Also in the collection, recently digitized by the presidential archives, are a transcript of Eichmann's defense counsel's Supreme Court appeal, the handwritten opinion of Justice Minister Dov Yosef, and a note by prosecutor Gideon Hausner for his opening address.
Israel marks its own Holocaust remembrance day, which this year will be held on May 4-5.
