Roadmap: Genocide and mass killings

  • Last time:
    • Human rights as a constraint that operates above the state
    • Any questions from Wednesday?
  • Today (and Wednesday)
    • What is genocide? Where does the concept come from?
    • What are the problems with the legal definition?
    • How has the concept been challenged?
    • An alternative: Valentino’s mass killing

What is genocide?

The history of the term “genocide”

  • Mass killing of groups is not a new practice, but the term “genocide” is

  • Raphael Lemkin coined “genocide” in 1944

    • Polish lawyer of Jewish descent
    • Deeply troubled by the deliberate destruction of national groups
    • Had proposed it as an international crime as early as 1933
  • He combined: Greek genos: “race” or “tribe” with Latin cide: “to kill”

Lemkin’s definition

  • Lemkin saw killing as only one of the many different techniques of genocide

  • Equally important: the systematic destruction of the foundations of a group’s life

” It is intended rather to signify a coordinated plan of different actions aiming at the destruction of essential foundations of the life of national groups, with the aim of annihilating the groups themselves. The objectives of such a plan would be disintegration of the political and social institutions, of culture, language, national feelings, religion, and the economic existence of national groups, and the destruction of the personal security, liberty, health, dignity, and even the lives of the individuals belonging to such groups. Genocide is directed against the national group as an entity, and the actions involved are directed against individuals, not in their individual capacity, but as members of the national group.

— Lemkin (1944)

Nuremberg trials (content note: some graphic images)

  • For discussion: What stands out to you about the tone of the video? How is it framed? Who is centered? Who is absent? Listen for what crimes are named. What is missing?
  • 1945: “genocide” appeared in the Nuremberg indictments due largely to Lemkin’s efforts
    • But it did not appear in the Tribunal’s Charter or the final judgment
    • No atrocities inside Germany or before September 1939 were prosecuted

From Nuremberg to the United Nations

  • 1946: UN General Assembly Resolution 96(I)
    • “A crime under international law, contrary to the spirit and aims of the United Nations”
    • Passed unanimously (53-0)
  • 1948: Convention on the Prevention and Punishment of the Crime of Genocide
    • The first human rights treaty adopted by the UN
    • Criminalizes genocide and obligates states to enforce its prohibition

The UNGC definition: Article II

“In the present Convention, genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group:

  • (a) Killing members of the group
  • (b) Causing serious bodily or mental harm to members of the group
  • (c) Deliberately inflicting conditions of life calculated to bring about physical destruction in whole or in part
  • (d) Imposing measures intended to prevent births within the group
  • (e) Forcibly transferring children of the group to another group”

The UNGC definition: too narrow? Too broad?

Think-pair-share: Lemkin versus UN definition

Lemkin (1944)

“…a coordinated plan of different actions aiming at the destruction of essential foundations of the life of national groups…disintegration of the political and social institutions, of culture, language, national feelings, religion, and the economic existence of national groups, and the destruction of the personal security, liberty, health, dignity, and even the lives of the individuals belonging to such groups.”

UNGC Article II (1948)

“…genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group: (a) Killing members of the group; (b) Causing serious bodily or mental harm; (c) Deliberately inflicting conditions of life calculated to bring about physical destruction; (d) Imposing measures to prevent births; (e) Forcibly transferring children.”

  • What does Lemkin’s definition include that the UNGC’s does not?
  • Which groups are not protected under Article II?
  • What are some potential problems with Lemkin’s definition? The UN definition?
  • Why might that matter?

Which groups qualify?

  • The UNGC covers: national, ethnical, racial, and religious groups

  • Conspicuously absent: political groups and economic classes

    • This was no accident: the USSR and others blocked their inclusion during drafting
  • Some of the bloodiest mass killings of the 20th century targeted political and class enemies:

    • Soviet Union: kulaks, “counterrevolutionaries,” Old Bolsheviks
    • China: landlords, “rightists,” “capitalist roaders”
    • Cambodia: “new people,” intellectuals, anyone with an education

How to define intent?

  • The UNGC requires intent to destroy a group “in whole or in part”

  • Two problems:

    1. Intent is extremely difficult to prove in court
    2. “In whole or in part”
  • Creates a very high bar for legal prosecution

  • Creates perverse incentives: perpetrators deny intent, claim security necessity instead

Crimes against humanity

  • Acts that are not classified as genocide can still be prosecuted as crimes against humanity

    • E.g., ethnic cleansing, enslavement, enforced disappearances, systematic persecution
  • Courts are often reluctant to classify events as genocide

  • So some perpetrators can still be prosecuted (no impunity gap)

  • However, some victims feel their suffering is diminished if “only” a crime against humanity

Critiquing definitions of genocide

Security justifications for state violence

  • Moses: Holocaust as not the only way to understand and define a genocide

  • Problem: most states do not claim to be killing civilians because they hate them

    • They claim the need to protect themselves from danger
  • Security logic and racial animus intersect

  • Permanent security: violent strategy where states eliminate perceived threats for safety

    • Helps justify ongoing, open-ended civilian killing
  • States routinely target civilians by invoking immediate and future threats

    • “They will organize resistance”
    • “The children will grow up and fight us”
    • “The population supports the insurgents”
  • This logic spans settler colonialism, bombing cities, even blockades or sanctions

The role of civilians in permanent security

  • Classical international law: civilians are presumed innocent

  • Total warfare logic: anyone in the area contributes to the war effort \(\rightarrow\) legitimate target

  • Moses: people do not need to be passive to be deemed innocent

    • Resistance to conquest does not forfeit your status as a civilian
  • Insurgency scenarios are the most common context for mass civilian killing

    • “The guerrilla must move amongst the people as a fish swims in the sea” — Mao Zedong

Applying permanent security and its implications

  • Narrow genocide definition \(\rightarrow\) “hierarchy of crimes”
    • Could possibly blind us to other systematic violence by powerful governments
  • The Violence of the Post-9/11 Wars (Crawford & Lutz, 2019):
    • Afghanistan & Pakistan, Iraq, Syria, Yemen: 300,000–400,000+ direct war deaths
    • Plus indirect deaths from infrastructure destruction, sanctions, disease
  • These deaths resulted from deliberate choices: aerial bombardment, blockades, sanctions

For discussion:

  • Does Moses’ framework apply here? Why or why not?
  • Should these be labeled as genocide or crimes against humanity? Why or why not?
  • How do definitions shape what gets scrutinized?
  • Why is the term genocide so powerful? Why is it so debated? Is this an issue?
  • Can genocide entail only the struction of culture without including killings of civilians?

Mass killing as an alternative concept for analysis

  • Mass killing: the intentional killing of a massive number of noncombatants

1. Intentional

  • Distinguishes it from natural disasters, disease outbreaks, or collateral damage
    • Includes indirect deaths (starvation, disease, exposure) if intentionally inflicted
  • Killing not necessarily primary goal, only reasonable expectation of mass death as result

2. Massive (at least 50,000 deaths within 5 or fewer years)

  • Arbitrary, but sets an objective and consistently applicable threshold

3. Noncombatants

  • Unarmed person not in an organized military group and not actively engaged in hostilities
  • Not associating with combatants (e.g., giving food) or participating in nonviolent activities
  • Perpetrators try to blur the line between combatant and noncombatant

What mass killing covers that genocide does not

  • Soviet, Chinese, Cambodian killings
  • Counterguerrilla campaigns
  • Strategic bombing and starvation blockades
  • Cases where perpetrators deny ethnic intent
  • Atomic bombings

However, the use of the term mass killing does not imply:

  • Moral or causal equivalency between genocide and mass killing
  • That genocide doesn’t matter; only that the concept is too narrow for causal analysis
