The UN has now voted to call the transatlantic slave trade the gravest crime against humanity. Britain did not support the resolution. The United States voted against it. That matters, because the argument now is no longer about whether slavery was evil. It is about whether the states that organised, financed and profited from it will continue to hide behind moral pageantry, legal evasions and selective memory.

Britain has spent years trying to tell this story backwards. The preferred national memory is neat, flattering and false. It begins not in the holds of slave ships, not in the ports that fattened on human cargo, not in the insurance houses and counting rooms that converted African suffering into British wealth, but in abolition. It begins with conscience, with reform, with parliamentary redemption. It begins, in other words, at the point where Britain tries to look least like the power it was.

That is precisely why the recent UN vote is so politically damaging. On 25 March 2026, the General Assembly adopted a Ghana-led resolution declaring the trafficking of enslaved Africans and racialised chattel enslavement of Africans the gravest crime against humanity. The resolution passed 123 to 3, with 52 abstentions. Britain abstained. The United States voted against. That alignment is revealing. London wanted enough distance to avoid the obscenity of an outright no, but not enough honesty to support the measure. Washington dispensed with the performance and opposed it directly.

The significance of Britain’s abstention is not procedural. It is moral and historical. Britain was not some peripheral participant in the Atlantic slave system. It was one of its paramount powers. British ships carried around 3.4 million Africans across the Atlantic. British merchants, ports, insurers and manufacturers drew immense gains from the trade. Liverpool, Bristol and London were not unlucky witnesses to someone else’s crime. They were built into its machinery. The slave trade was not a regrettable side note to British development. It was part of the engine.

This is what the national story is designed to conceal. Britain did not first encounter slavery as a moral scandal and then rise against it. Britain helped make the trade one of the decisive commercial systems of the Atlantic world. It turned maritime reach, financial innovation and imperial appetite into a structure of organised kidnapping, forced transport and coerced labour. Sugar, shipping, dock infrastructure, insurance, credit, manufacturing and overseas plantation wealth all fed into the enlargement of British power. A nation that wants to begin the story at Wilberforce is a nation trying to avoid beginning it at Liverpool.

The legalistic answer now advanced by Britain is a clever one, but a dishonourable one. In its explanation of vote, the UK government said it could not support the resolution because it rejected creating a hierarchy of historical atrocities and because, under intertemporality and non-retroactivity, there is no duty to provide reparation for acts that were not illegal under international law at the time they occurred. It also rejected the attempt to move around that obstacle through the language of continuing harm. This is the sort of argument states reach for when they know the moral ground beneath them is weak. It is not an answer to the substance. It is a containment strategy.

Stripped of diplomatic language, Britain’s position is this: the wealth, status and institutional inheritance generated under empire may continue, but the obligation arising from the crimes that helped generate them must not. Continuity for assets. Discontinuity for responsibility. That is the real doctrine. Britain wants inheritance without liability. It wants the proceeds of empire without the burden of historical reckoning. It wants the right to narrate itself as a mature liberal democracy while refusing to confront the material foundations of the order from which it still benefits.

The American position is even uglier because it is more explicit. The United States voted against the UN resolution and relied on the same narrow legal logic: no legal right to reparations for historical wrongs that were not illegal under international law at the time. This is a brutal argument from a state whose early economic expansion, territorial consolidation and political order were deeply shaped by slavery and its aftermath. The United States is not defending a principled legal boundary here. It is defending insulation for a founding crime.

Both countries rely on the same move. They universalise morality outward and contract it inward. They preach accountability to weaker states, invoke human rights when politically useful, and wrap themselves in the language of justice and rules. But when the light falls on the crimes that formed their own wealth, the tone changes. Suddenly history becomes complicated, liability becomes impossible, causation becomes too diffuse, and the practicalities become prohibitive. This is not moral seriousness. It is rank power behaviour disguised as prudence.

Britain’s self-exculpation has an additional layer of sentimentality. It has long been tempted by the fantasy that abolition wipes the slate clean. That because Britain eventually moved against the slave trade, it can stand in history chiefly as the nation that ended slavery rather than as one of the nations that profited most from it. But abolition after centuries of enrichment does not erase the enrichment. Ending a racket after amassing fortune from it does not turn the operator into a redeemer.

And Britain did not even abolish slavery in a morally clean way. When slavery was ended in the British colonies, the state compensated slave owners, not the enslaved. That single fact should end most of the sentimental evasions. A state truly acting in justice would have centred those whose lives and labour had been stolen. Britain instead moved first to protect property interests. Slave owners received compensation on an enormous scale. The enslaved received freedom stripped of restitution. The empire did not merely end a system. It managed its transition in a way that shielded capital.

This is why the UN vote matters beyond symbolism. The argument has shifted. For years Western governments were able to treat reparations as an activist slogan, an academic demand, or a rhetorical pressure tactic with little institutional traction. That position is becoming harder to sustain. African states have pushed the issue through the African Union. Caribbean states have kept it alive through CARICOM’s programme of reparatory justice. Ghana has now driven the argument into the General Assembly itself. The effect is cumulative. The old Atlantic powers are being forced to state their position more openly, and what they are saying is not attractive.

Britain’s abstention is often treated as a middle course. It is not. It is an attempt to enjoy the reputational benefits of not voting no while still refusing to back the principle in any serious way. Abstention is often the preferred tactic of states that sense the moral climate moving against them but are unwilling to accept the consequence of that movement. It is the diplomacy of controlled embarrassment. Britain wants to look civilised while holding the line against substantive implications. But the line is still a line of resistance.

The defence that present governments cannot be held liable for historic crimes is not entirely frivolous in legal terms. Opponents of reparations are right to say that there are serious issues of intertemporal law, causation, quantification and institutional competence. There is no neat court-ready formula that turns four centuries of slavery, colonial extraction, underdevelopment and racial hierarchy into one simple damages award. Any advocate who pretends otherwise weakens the case. Law is not a magic machine that converts moral truth into arithmetic certainty.

But that is exactly why Britain’s position is still so poor. Because the absence of an easy legal mechanism does not absolve a state of political and moral responsibility. Reparations are not reducible to one cheque, one tribunal or one headline figure. They can involve apology, archival truth, educational investment, debt relief, health support, institutional reform, cultural restitution, memorialisation and long-term developmental repair. Britain behaves as though the only choices are either to reject all responsibility or to surrender to an unlimited damages claim. That is a false binary designed to protect inaction.

The deeper issue is narrative control. Once slavery is placed back at the centre of the rise of Britain and the United States, the flattering self-image of the Atlantic powers starts to crack. Britain becomes harder to describe as the island nation of liberty that corrected the world. It starts to look again like what the record shows: a maritime empire that converted coercion, extraction and racial hierarchy into durable power. The United States becomes harder to describe simply as a republic that overcame a contradiction. It begins to look again like a state whose wealth and institutions were shaped by slavery and by the racial order that followed it.

That is what London and Washington are resisting. Not merely a resolution. Not merely the word reparations. Not merely a set of awkward diplomatic conversations. They are resisting a revised baseline story about themselves. They know that once slavery is treated not as a regrettable chapter but as an organising fact in the making of modern Western wealth, everything else becomes less comfortable: the museums, the universities, the estates, the banks, the family fortunes, the language of national virtue, the global human-rights posture, the imperial nostalgia.

And that is why Britain’s abstention deserves to be read harshly. Britain did not merely fail to support an anti-slavery resolution in some abstract moral vacuum. Britain abstained on a resolution condemning a system in which it was one of the leading powers and from which it enriched itself greatly. The country that loves to foreground its abolitionist inheritance would not support a UN declaration on the gravest crime against humanity when that declaration sharpened the question of accountability. The contradiction is not minor. It is the whole point.

The United States, meanwhile, has chosen a still cruder posture: open resistance. At least Britain felt the need to disguise its refusal. Washington has preferred to plant itself directly on the side of legal insulation. That tells you something about the confidence of American power and something else about the poverty of its moral imagination. A state that cannot face the continuing structure of advantage created by slavery will always reduce justice to a technical argument about when the crime officially counted.

None of this means that every reparations demand is automatically sound, every monetary estimate is automatically serious or every political programme framed under that banner is automatically wise. It does mean that the central Western refusal now looks thinner by the year. The old answer – too old, too difficult, too complicated, too expensive – is beginning to sound less like prudence and more like fear. Fear of precedent. Fear of exposure. Fear of narrative loss. Fear that the world is no longer willing to let the architects and beneficiaries of historic plunder write the final moral summary themselves.

Britain should therefore stop hiding inside abolition. Its true place in this history lies not only in parliamentary reform but in the ships, the docks, the plantations, the ledgers and the fortunes. It lies in the central role it played in carrying enslaved Africans across the Atlantic and in the immense wealth that role helped to generate. It lies in the choice to compensate owners rather than the enslaved. And it lies now in the decision to abstain when the international community moved to name the crime in the strongest possible terms.

A state does not wash itself clean by eventually discovering conscience after centuries of profit. Britain did not become great by abolishing slavery. It became great in no small part by running, financing and profiting from it. That is the truth beneath the national pageantry. And until Britain and the United States can confront that truth without legal camouflage, their lectures on human rights will continue to sound like the voice of power demanding moral exemption from its own past.
