In remarks at a UNESCO luncheon in October 2015, Kerry said “I had lunch the other day with Henry Kissinger and he obviously continues to amaze all of us.”

Less than two weeks later, in a speech at the Carnegie Endowment for International Peace, Sec. Kerry again noted that he had just recently “had the privilege of having lunch with” Kissinger, whose books Kerry said influenced him.

Even before he became secretary of state,  Kerry applauded Kissinger. In his testimony before the Senate Committee on Foreign Relations as a nominee for the position, Kerry cited Kissinger and “his superb book on diplomacy.”

Nor are Clinton and Kerry alone. Samantha Power, who worked in the Obama administration’s State Department and now serves as the U.S. ambassador to the U.N., has even gone to baseball games with Kissinger.

At age 92, Kissinger is one of the longest-serving statesmen in U.S. history. Since 1969, the accused war criminal has played an important role as a foreign policy advisor in most, if not all U.S. presidential administrations. Still today, Kissinger works with the Obama administration.

Thanks to the work of historians, however, we now know much more about the atrocities Kissinger oversaw while in office.

As just some of the myriad examples of his crimes, in “The Trial of Henry Kissinger,” Hitchens documented Kissinger’s implications in the following:

1. The deliberate mass killing of civilian populations in Indochina.
2. Deliberate collusion in mass murder, and later in assassination, in Bangladesh.
3. The personal suborning and planning of murder, of a senior constitutional officer in a democratic nation — Chile — with which the United States was not at war.
4. Personal involvement in a plan to murder the head of state in the democratic nation of Cyprus.
5. The incitement and enabling of genocide in East Timor
6. Personal involvement in a plan to kidnap and murder a journalist living in Washington, D.C.

This only scratches the surface.

It is now known that, in the 1970s, Kissinger met with Nazis to give advice on how to overthrow the left-leaning West German government.

While the Khmer Rouge was carrying out a campaign of genocide in Cambodia, Kissinger backed it, in an effort to crush the Vietnamese Communists. “You should tell the Cambodians that we will be friends with them. They are murderous thugs, but we won’t let that stand in the way,” Kissinger remarked in 1975. “We are prepared to improve relations with them.”

Moreover, Kissinger assured far-right, authoritarian Latin American governments that the U.S. would support them, helping them “to succeed” in Operation Condor, their systematic campaign of state terrorism against left-wing movements.

And when Cuba assisted Angola in its fight for independence from colonial Portugal in 1975, Kissinger wanted to “clobber Cuba” and “smash Castro.”

Kissinger and  Nixon ordered the U.S. government to “make the economy scream” in Chile, when the country democratically elected a socialist government. “The issues are much too important for the Chilean voters to be left to decide for themselves,” Kissinger declared, while overseeing the violent overthrow of Chilean democracy.

On the 40th anniversary of the Sep. 11, 1973 CIA-backed coup that installed far-right dictator Augusto Pinochet, Kissinger met with Secretary of State John Kerry to advise him on U.S. policy in Syria.

Because of these crimes, there are countries to which Kissinger avoids traveling, for fear of being arrested.

In many ways, Clinton is a disciple of Kissinger and his aggressive, so-called “realist” school of foreign policy. Just as Clinton has overseen destructive wars and continuously pushed for military-heavy positions on Syria, Ukraine and more, Kissinger promoted a “madman” strategy in Vietnam, trying to make enemies believe the U.S. “might be crazy” enough to use a nuclear bomb.

One email, in fact, suggests that, as secretary of state, Clinton saw Kissinger as her role model. In a December 2009 message, Clinton speaks of the Nixon-Kissinger partnership as the ideal, mourning the fact that her partnership as secretary of state with President Obama was not as close. “In thinking about the Kissinger interview, the only issue I think that might be raised is that I see POTUS at least once a week while K saw Nixon everyday,” Clinton wrote. “Do you see this as a problem?”
