Yugoslav Wars and Dayton Peace Agreement

Slovenia was ethnically homogeneous, on the border with Austria and Italy, and had no Serb population to protect, so Belgrade fought for ten days and let it go. The decision to concede here and fight elsewhere was a calculation about which territory was worth an army.

An eighty-seven day siege destroyed a town of fifty thousand and demonstrated to every other community what resistance would cost. Sieges of this kind are conducted for their demonstration effect as much as for the ground, and the message was received across Croatia and Bosnia.

Bosnia had no army, its territory was indefensible and its three communities were armed to very different degrees. Recognising it as a state did not give it the means to be one, and the war that followed was fought over whether it would exist at all.

The force was authorised to escort aid and not to stop the war, which meant it fed people while their towns were taken. Sending soldiers with a mandate that excludes the purpose everyone can see is a way of appearing to act, and it was understood that way.

The Council created a court while declining to stop the killing, and the tribunal's establishment was widely read at the time as a substitute for action. A gesture that costs little may nonetheless produce an institution of real consequence, which is what happened here.

American pressure ended the Croat-Bosniak war and created a single opponent for the Bosnian Serbs, changing the military balance decisively. Turning two of three belligerents into one is the manoeuvre that made the eventual settlement possible, and it was a power-political intervention.

A United Nations safe area was taken by a force of a few thousand while a Dutch battalion of six hundred lightly armed troops watched, air support having been refused. Guarantees without capability behind them fail at the moment they are tested, and this is the definitive case.

Three presidents were confined to an Ohio air base for twenty-one days after NATO bombing and Croat-Bosniak offensives had changed the map. The settlement recorded a balance newly created by force, which is why it succeeded where three years of proposals had failed.

Yugoslavia's coherence had rested on Tito, on the threat from both blocs and on external credit, and by 1991 all three had gone. States held together by an external pressure tend to come apart when it lifts, and the Cold War's end removed the pressure across eastern Europe.

The Yugoslav army inherited the federation's weapons and Croatia had almost none, and an arms embargo imposed on all parties froze that asymmetry. Neutral measures applied to unequal parties entrench the inequality, which was the embargo's practical effect throughout.

Bosnia's Serbs had the federal army's weapons and Belgrade's support; the government had neither and was denied arms by the embargo. The military imbalance at the outset determined the map for three years, and every diplomatic proposal reflected the ground rather than the principle.

Peacekeepers on the ground became hostages, and the fear of losing them constrained the air power that might have changed the situation. Deploying vulnerable forces without the will to protect them creates a hostage problem that paralyses the states that sent them.

The tribunal had no police and depended on states to arrest suspects, so its early years produced few defendants. Enforcement of international criminal law runs through the capabilities of states, and it improved only when NATO forces in Bosnia began making arrests.

Croatia was permitted to rearm and to train, and its offensives in 1995 shifted the territorial position that Dayton then froze. The diplomacy followed the balance, and the balance was altered deliberately by the state doing the mediating.

Requests for close air support went through a dual-key procedure requiring both United Nations and NATO approval, and were delayed and refused. Command arrangements designed to reassure contributing states prevented the force from acting when acting mattered.

Two weeks of NATO air strikes did what three years of diplomacy had not, because they altered what the Bosnian Serb leadership could expect. Coercion and negotiation worked together here, and neither would have produced the agreement alone.

Slovenia and Croatia held referendums with overwhelming majorities for independence, invoking the self-determination that the federal constitution itself acknowledged. Every party could cite a principle, and the question of which unit holds the right to self-determination has no legal answer.

Two hundred and sixty patients and staff were taken from the hospital and killed at Ovcara, an atrocity documented in detail and later prosecuted. Establishing the record at the time made the prosecutions possible, which is an argument for observers even where they cannot protect.

A referendum boycotted by one of three constituent peoples produced a majority for independence, which was constitutionally proper and politically fatal. Majority procedures in a society divided three ways deliver outcomes that a third of the population regards as illegitimate.

Western publics saw camps, shelled markets and besieged cities nightly and demanded that something be done, and their governments did the minimum that looked like something. Opinion produced humanitarian action precisely because it was cheaper than the military action opinion was actually demanding.

The court gave victims a forum and produced an evidentiary record of enormous scale, including the testimony of thousands of witnesses. Whatever its limits, it established facts in a form that political denial has not been able to dislodge.

The federation created cantons, power sharing and complex guarantees for two communities that had just been fighting. Constitutional engineering of this kind can stop a war and it produces governments that are slow, expensive and prone to deadlock.

More than eight thousand men and boys were separated, transported and killed over several days, and the women and children were expelled. This was administered rather than chaotic, requiring buses, lists and burial sites, and the organisation is what made it a genocide in law.

The agreement created a state with two entities, three presidents, thirteen governments and a high representative able to override them all. It ended the war and produced a constitution so complex that thirty years later the country still cannot function normally.

The European Community's Badinter Commission ruled that Yugoslavia was in dissolution and that republic borders would become international ones. That rule determined the shape of the wars, since it made Bosnia's borders inviolable and its internal divisions irrelevant in law.

European monitors and mediators were present throughout the siege, negotiating a succession of ceasefires that were announced and then broken within days. Mediation without leverage produces agreements that document the parties' stated intentions and change nothing whatever about their conduct, and fourteen such ceasefires were signed during 1991 alone.

Recognition proceeded on the Badinter criteria without any mechanism to protect the state being recognised. Conferring status without capacity or protection created an internationally recognised state under immediate siege, which is a considerable institutional failure.

Safe areas were declared for six towns without the troops the commander said were needed to defend them, a fraction of which were provided. Creating an obligation without resourcing it is worse than declining it, because it induces reliance that cannot be honoured.

Creating the tribunal by Security Council resolution rather than by treaty was legally innovative and much faster, and the same device was used for Rwanda a year later. Institutional improvisation under Chapter VII created the precedent that led to the permanent court.

The agreement bundled a ceasefire, a constitution and a confederation with Croatia into a single package, so that each party's gain was contingent on the others. Linking concessions across issues is how mediators create bargains that unbundled negotiation cannot reach.

Dutch, French and United Nations inquiries afterwards each documented institutional failure, and the Dutch government resigned in 2002 over its report. Accountability arrived years later and reached the sending states as well as the perpetrators, which is unusual.

Dayton bundled military annexes, a constitution, refugee return, elections, human rights machinery and an implementation force into one instrument with a single signature. Comprehensive packaging is why it held: no party could accept part and reject the rest.

Recognition was the instrument that mattered, and Germany's pressure for early recognition of Slovenia and Croatia has been argued about ever since. Deciding when an entity becomes a member of international society is among the society's most consequential collective acts.

This was the first European city destroyed by artillery since 1945, and it was done in front of monitors from the states that had spent forty years building the continent's security order. That the society could observe and not act defined the next four years.

A member of the United Nations was attacked, besieged and partitioned by force while the society of states debated whether this was a civil war or an aggression. The category chosen determined what response was owed, and the ambiguity was convenient.

The society of states substituted humanitarian relief for the protection its own rules implied it owed a member under attack. That substitution, aid instead of enforcement, became the defining criticism of the 1990s and drove the later doctrine of responsibility to protect.

The first international criminal tribunal since Nuremberg was created for a conflict in Europe, and it revived a dormant principle after forty-eight years. International society reactivated individual criminal responsibility, and it has not since been able to put it away.

The United States displaced the Europeans as the mediator in a European war, having spent three years declining involvement. Who mediates is a question about standing in international society, and the transfer here was noticed in every European capital.

The tribunal and the International Court of Justice both found genocide, the only such finding for the Yugoslav wars. International society named the crime and thereby accepted that its own failure to prevent it engaged the Genocide Convention's duty.

The settlement preserved Bosnia's international borders while conceding almost everything about its internal structure to the parties that had fought to divide it. International society defended the shell of sovereignty and accepted a hollowed-out interior.

A decade of nationalist media, historical grievance and manufactured fear had already made the federation's shared identity unavailable. Yugoslavia did not dissolve because of ancient hatreds but because political entrepreneurs had spent years constructing the categories that made it impossible.

Vukovar became a founding trauma of Croatian national identity and is commemorated annually, its ruined water tower left standing. What such a place is made to mean afterwards shapes politics for decades, and it was preserved deliberately.

Ethnic cleansing entered the language here, a term coined to describe the deliberate removal of populations to make territory homogeneous. Naming the practice was a precondition for treating it as a crime, and the naming happened during the events.

Calling places safe areas created an expectation among the people sheltering in them that proved false. Words used by international institutions carry promises, and the gap between the promise and Srebrenica is the reason the term is now avoided.

Indicting sitting heads of state and eventually trying Milosevic changed what political leaders could assume about their own immunity. The expectation of impunity, which had been near-absolute, became merely probable, which is a real change.

Bosniaks and Croats had fought a vicious war within the larger one, including the destruction of the bridge at Mostar. Reconstituting them as partners required a reframing imposed from outside, and the federation's institutions have carried the strain ever since.

Srebrenica became the reference case for every subsequent argument about intervention, invoked in Kosovo, in Darfur and in Libya. What the massacre came to signify, the cost of standing by, changed the politics of intervention for a generation.

Dayton froze the wartime ethnic map into constitutional categories, making Bosniak, Serb and Croat the basic units of citizenship. Institutionalising the identities the war produced was the price of peace, and it has made overcoming them structurally impossible.
