Quoting John Judge’s Good Americans:

Henry Kissinger — Worked with General Lucius Clay at Oberammergau, and then with key stateside Army Intelligence and CIA units responsible for bringing in the Nazi spies.[45] Kissinger, who came from Germany to join U.S. Army Intelligence during World War II, had as his “mentor” the mysterious Fritz Kraemer.[46] Kraemer’s 30-year silent career in the Pentagon plans division includes the prepping of Alexander Haig.[47] It may also conceal his real identity – prisoner #33 in the dockets at Dachau, the special Lieutenant to Hitler, Fritz Kraemer.[48] Mr. Kissinger still relie[d] on his advice, and did so while Secretary of State.

(Emphasis original. Some sources like Wikipedia still insist that the Kraemer advising Kissinger was completely unrelated to the Axis war criminal, but this assertion is dubious. See Jonathan Vankin and John Whalen The 80 Greatest Conspiracies of All Time: History’s Biggest Mysteries, Coverups & Cabals, chapter 78 for information on that.)

Kissinger might have been the one who sent Walter Rauff to Chile to advise the DINA. Even if not, he was tellingly disinterested in doing anything about Rauff. Quoting Daniel Stahl’s Hunt for Nazis: South America’s Dictatorships and the Prosecution of Nazi Crimes, page 207:

When [John Cole] heard [that] Kissinger was planning a South American trip in April 1975, he wrote and asked him to raise the subject of Rauff during his stop in Chile.107 But the State Department thought it inappropriate to get involved, arguing that the extradition of the [Axis] criminal was solely a matter for the West German and Chilean justice systems.108

Kissinger also collaborated with the self‐identified fascist Licio Gelli. Quoting Daniele Ganser’s NATO’s Secret Armies: Operation Gladio and Terrorism in Western Europe, pages 74–5:

According to the document Nixon’s Military adviser General Haig, who had commanded US troops in Vietnam and thereafter from 1974 to 1979 served as NATO’s SACEUR, and Nixon’s National Security Advisor Henry Kissinger ‘authorized Gelli in the fall of 1969 to recruit 400 high ranking Italian and NATO officers into his Lodge’.60

It may strike some as incredible that Kissinger, who was of Jewish background and even fled the Third Reich, would have anything to do with former Axis personnel. Yet in addition to the evidence above, his opinion on Soviet Jews suggests that he saw his own kin as liabilities!

Kissinger himself had very little sympathy for the […] Jews in the Soviet Union.

The emigration of Jews from the Soviet Union is not an objective of American foreign policy. And if they put Jews into gas chambers [there], it is not an American concern. Maybe a humanitarian concern.

Henry Kissinger has come under fire for his comments on Soviet Jewry on the Nixon tapes, but he reminds us that by working with the problem of Soviet Jewry as a humanitarian problem, as opposed to an American problem, he was able to arrange for 40,000 Jews to leave the Soviet Union.

What he fails to mention is that the vast majority of those Jews went to the State of Israel, not America. There they faced great disappointment as they realized that the Zionist state was not the paradise they had been told about.

Economically, they had been much better off in the Soviet Union. Many of them were educated and talented and had jobs in the Soviet Union that required technical expertise. In the Zionist state, these fields were saturated and they were left unemployed or sweeping the streets.

ETA:

In 1985, he publicly supported President Ronald Reagan’s wreath-laying ceremony at a military cemetery in Bitburg, West Germany where members of the Waffen-SS are buried. Kissinger opposed the idea of a United States Holocaust Memorial Museum, because such an institution next to the National Mall in Washington, D.C., might create “too high a profile” for American Jews and “reignite antisemitism.”

[…]

Walter Isaacson explains that at a contemporaneous meeting of the Washington Special Actions Group, a government crisis task force, Kissinger grumbled, “If it were not for the accident of my birth, I would be antisemitic.” He added: “Any people who has been persecuted for two thousand years must be doing something wrong.”

Remember that the upper classes always serve theirselves first and foremost, not ordinary people incidentally related to them in some (very distant) way.
