Jus ad bellum
Justice (in going) to war
What would justify going to war?
Jus in bello
Justice in war
What are the rules of conduct in war?
Arguments that War is
sometimes justifiable
Rectificatory justice
How can you right a wrong?
Rectificatory justice
How can you right a wrong? Aristotle:
– This must be done by a proper authority: a
judge with authority to adjudicate
– It is for a just cause: there must have been an
injustice that harmed someone
– It is intended for a just purpose: to set things
right again, to make things as if the injustice had
never occurred
Going to war
Just war theory (Aquinas): Classic answer,
based on rectificatory justice
A war is just if:
– It is waged by a proper authority
– It is for a just cause: the enemy deserves to be
attacked for some fault
– It is intended for a just purpose: to advance
good and avoid evil
Proper Authority
A war must be waged by a proper authority
Wars must be waged by legitimate
governments or international organizations
granted such authority by legitimate
governments (e.g., NATO, the UN)
Decisions to go to war must be made by
proper authorities within those governments
or organizations
Just Cause
Wars must be fought for just causes, on
account of faults
Faults that might justify war:
– Aggression (countries may defend themselves,
their citizens, or one another, against attacks)
– Danger (countries may attack a country
preemptively if it endangers them?)
– Human rights (countries may defend citizens
from violations of their rights?)
Just Purpose
Wars must be intended for just purposes: to
advance good and avoid evil
Wars must be waged, not for self-interest,
but because it’s the right thing to do
Good purposes:
– Restore peace
– Defend citizens
– Save lives
– Advance freedom and democracy
– Protect human rights
Just wars: World War II
Allies waged war by proper
authority: official
declarations of war by
legitimate governments
Just wars: World War II
Just cause: response
to attacks (Germany
attacked Poland,
Norway, Denmark,
Belgium, the
Netherlands, France,
Russia, and Britain;
Japan attacked China,
various East Asian
countries, and the
United States)
Just wars: World War II
Just purpose: intended
to stop aggression and
restore peace
Unjust wars
Lack of just authority: Those not waged by
the proper authority
– Rebellions, revolutions not authorized by any
legitimate body
– Wars waged by illegitimate governments
– Private wars, vigilante actions
No just authority: Che Guevara
No just authority: Sept. 11
Unjust wars
Lack of just cause: Those not in response
to some fault
– Wars of aggression (Italy attacking Ethiopia;
Germany attacking Poland et al.; Japan
attacking China & the US; North Korea
attacking South Korea; Iraq attacking Kuwait)
– Wars based on misunderstanding
– Wars to maintain unjust control (USSR invading
Hungary, Czechoslovakia)
Aggression: Blitzkrieg, 1940
Unjust control: Hungary, 1956
Unjust wars
Lack of just purpose: Those waged for a
reason other than seeking good and
avoiding evil, e.g., revenge, hatred, envy,
aggrandizement, cruelty, the fever of revolt,
the lust for power
Unjust Purpose: Iran-Iraq War, 1980
Unjust Purpose: Napoleon’s
Invasion of Russia, 1812
Unjust Purpose: Hitler’s Invasion
of Russia, 1941
Unjust Purpose: Iraq’s Invasion
of Kuwait, 1990
Hugo Grotius (1583-1645)
On the Law of War and
Peace: “The grounds
of war are as
numerous as those of
judicial actions. For
where the power of law
ceases, there war
begins.”
Justifiable Causes of War
Defense: “Injury, or the
prevention of injury, forms the
only justifiable cause of war.”
Indemnity: right to recovery,
redress, damages,
compensation for injury
Punishment: punish
aggressor, deter future
aggressors
How does injury justify war?
Principle of self-preservation:
you may kill an aggressor if
– you are threatened with
immediate danger
– the danger can’t otherwise be
avoided
Aggressor forces people to
risk their lives for the sake of
their rights
Aggression justifies forceful
resistance
The Domestic Analogy
There exists a society of independent states
This society has a law establishing rights of its
members
Any use of force, or immanent threat of force,
by one state against another is a criminal act
Aggression justifies wars of self-defense and of
law enforcement
Nothing but aggression can justify war
Aggressors can be repulsed and punished
Arguments for Pacifism
Mahatma Gandhi (1869-1948)
Ahimsa: Non-violence
“Non-violence is
infinitely superior to
violence.”
Gandhi argues for
pacifism: violence is
morally unacceptable
The Ethics of Killing
Killing is intrinsically
wrong
The only exception: when
it is in the interest of the
one being killed
Even then, it would be
hard to have confidence
that killing is right
Deontological Arguments
It is wrong to cause
pain or kill
– Out of anger
– For a selfish purpose
– Or with the intention of
harming it
Non-violence ennobles
those who lose their
lives
Consequentialist Arguments
Non-violent responses to
aggression defuse anger
It is not weakness, but
pitting oneself against
the will of the tyrant
It can achieve political
objectives
In the long run, it results
in the least loss of life
When Killing is Justified
One must destroy life
to live— but one
should do it as little as
possible
One can kill to stop
suffering
One can kill a crazed
person running amok
Justifying War
Some wars are justified:
WWII, Korea
But the future is unpredictable
Unforeseen effects always
outweigh foreseen effects
So, it’s impossible to know, at
the time, that a decision to
use violence is justified
Objections to Pacifism
If killing is wrong, it must be because life has
value
But then why can’t someone kill to protect or
defend life?
Orwell: Gandhi gained independence for
India, but from the British— would it have
worked against a ruthless, totalitarian foe?
How can a pacifist protect the persecuted?
Preventive War
Can one ever attack first?
Talmud: “If a man is coming to kill you, wake
up early and kill him first.”
Against Preventive War
Preventive war presupposes a
standard for measuring danger
Fought to maintain balance of
power
Utilitarian argument:
– The balance of power maintains
order that makes liberty possible
– Fighting early reduces cost of
defense
Against Preventive War
Second-level utilitarian argument:
– Accepting that argument leads to
countless wars whenever shifts in
power relations occur
– Threats might justify war, but fear
doesn’t; how can we tell them
apart?
– It’s best to rely on legalist paradigm
For Preventive War
Sometimes, it really is less
costly to fight early
Example: Nazi occupation of
Rhineland, 1936; WWII could
have been prevented
It’s hard top gauge likelihood or
magnitude of future attacks
But cost the attack will impose,
multiplied by probability, may be
very high
For Preventive War
Suppose there’s a 50%
chance of an attack
Cost of that attack: 100
Expected cost: 50
If a preventive war would cost
less than 50, it’s justified
For Preventive War: Terror
This argument is especially
strong when applied to
terrorism
Terrorists can do vast damage
Retaliation and deterrence are
difficult
– Hard to track who’s responsible
– Terrorists may be widely
dispersed
– Suicide bombers can’t be
punished after the fact
For Preventive War
Domestic analogy: we punish
people for planning to commit
crimes
Evidence has to be convincing, but
standard is weaker for violent
crimes
Individuals who can’t be deterred
can be punished in advance
Jus in bello
What are the proper rules of
warfare?
Walzer: That one may not shoot
someone in the act of
surrendering shows that there
are such rules
Not everything is permitted
“War is distinguishable from
murder and massacre only
when restrictions are
established on the reach of
battle.”
Jus in bello
When and how can soldiers kill?
Walzer: This appears largely
conventional.
Limitations of weapons (e.g.,
chemical and biological weapons
treaties); limitations on
questioning, torture
But are these merely
conventional?
Treatment of prisoners
235,000 American and British prisoners were
held by the Germans and Italians; 4% died
132,000 were held by the Japanese; 27% died
American aircraft machine-gunned Japanese
survivors swimming for shore; Americans often
shot surrendering Japanese
Japanese doctors performed horrendous
experiments on prisoners
Johnson: “moral confusion”
Rules of War
Whom can they kill?
War is a combat among
combatants
Killing someone not currently
engaged in the business of
war is a crime
Rules of War
Grotius: we may
defend ourselves
against allies of our
enemy
We may attack even
when the attack
endangers innocent
lives
Von Clausewitz
War is an act of violence
intended to compel our
opponent to fulfill our will
Object is to disarm the
enemy
War is a political act, “a
mere continuation of
policy by other means”
All’s fair in war
“…in such dangerous things as War,
the errors which proceed from a
spirit of benevolence are the worst.”
Nice guys finish last: “…he who
uses force unsparingly, without
reference to the bloodshed involved,
must attain a superiority is his
adversary uses less vigour in its
application.”
Virtue in war is not a means
“…to introduce into the
philosophy of War itself a
principle of moderation would
be an absurdity.”
Prussian General von Moltke:
“The greatest kindness in war
is to bring it to a speedy
conclusion.”
Hard Cases: Enemy Cities
Roosevelt, 1939:
Asked belligerents to refrain from the “inhuman
barbarism” of bombing civilians
But that attitude didn’t survive for very long
Hard Cases: German Cities
Churchill, July 8, 1940:
“When I look round to see how we can win the
war I see that there is only one sure path. . . .
[T]here is only one thing that will bring [Hitler]
back and bring him down, and that is an
absolutely devastating, exterminating attack by
very heavy bombers from this country upon the
Nazi homeland.”
Hard Cases: German cities
Historian Paul Johnson:
“The policy . . . marked a critical stage in the
moral declension of humanity in our times.”
Took about 25% of Britain’s war production;
killed 600,000 Germans
Hamburg, night of July 27-28, 1943: 8001000° C over the city; destroyed half the
housing, 37.65% of the population killed
Hard Cases: Dresden
February 13-14, 1945: over
650K incendiaries dropped
on the city
Firestorm engulfed 8 square
miles, killed 135,000 men,
women, and children
There were not enough
survivors to bury the dead
Goebbels: “It is the work of
lunatics.”
Pilots: “It was the only time I
felt sorry for the Germans.”
Dresden: before
Dresden: after
The Bombing of Tokyo
March- July 1945:
100K tons of
incendiaries dropped
on 66 cities, wiping out
170,000 square miles
of densely populated
streets, killing 260,000
March 9-10, 1945:
killed 83,000 in Tokyo,
injured 102,000

Hard Cases: Hiroshima
Oppenheimer, quoting the
Bhagavad Gita: “I am become
as death, the destroyer of
worlds.”
August 6, 1945, 8:15am: out
of 245,000, 100,000 died
immediately, 100,000 died
subsequently
August 9: Nagasaki, 75,000
killed
Utilitarian justification
June 6, 1945: Japanese Supreme Council
approved plan to “prosecute the war to the
bitter end”
10,000 suicide planes; 2 million troops on
the beaches; 4 million tropps, 28 million
militia in reserve
Allies projected 1 million American
casualties, 10-20 million Japanese
