Why Hate Against Jews in Britain Meets the Threshold of Crimes Against Humanity

Two years after 7 October, Britain lives with the aftershocks of a massacre that began as an attack on Jewish civilians and then metastasised into pressure on Jewish life far from the battlefield. What followed in the UK was not a normalised policy debate about Gaza. It was a surge of targeted hostility, intimidation, and explicit calls for violence directed at Jews and Israelis as Jews, a pattern that Britain’s leading monitoring body describes as unprecedented in scope and persistence. The question we have been avoiding—legally as much as morally—is whether such conduct is merely “hate crime” in the ordinary domestic sense, or whether, given its organised nature, scale, and connection to an ongoing campaign against a recognisable civilian population, it has crossed into the territory of crimes against humanity, specifically persecution. On the evidence, there is now a serious argument that it has.

Begin with what is measurable. The Community Security Trust (CST) recorded the worst year for antisemitism since records began, with the sharpest acceleration immediately after 7 October; that step-change did not revert to prior baselines but persisted deep into 2024–25. In the twelve months after 7 October, CST logged 5,583 incidents, a year-on-year jump of 204%, a shift so marked that mainstream demographers say it altered the emigration calculus of British Jews. On defined days of mobilisation, spikes were visible: after a Glastonbury chant of “Death, death to the IDF” (the Israel Defense Forces) there was a same-day peak in incidents, illustrating how performative hostility in public arenas bleeds directly into street-level harassment and assault. The Government has responded by expanding security funding to Jewish schools and synagogues—an implicit recognition that heightened threat is not speculative but current. None of this is mere “offence”; it is a pattern of targeted pressure on a civilian minority in Britain, temporally and causally linked to a foreign armed group’s attack on Jews as such. 

Now the law. Under Article 7 of the Rome Statute, a crime against humanity means certain enumerated acts when committed as part of a “widespread or systematic attack directed against any civilian population,” with knowledge of that attack. Among those acts is persecution, defined as the intentional and severe deprivation of fundamental rights by reason of the identity of the group. The Elements clarify that persecution may be committed “in connection with” other acts listed in Article 7 and must occur within a wider attack—but the mode need not be kinetic; severe rights deprivations and campaigns of intimidation may qualify, where they are widespread or systematic and identity-based. 

What Britain has witnessed since 7 October—a sustained, identity-targeted campaign of intimidation and violence-adjacent rhetoric aimed at Jews and “Zionists” in the UK, timed to and choreographed with the military campaign of a proscribed terrorist organisation—maps disturbingly onto the persecution paradigm. When demonstrators chant for the death of Jews or Israelis, when professionals publicly praise the 7 October mass killing, and when organised networks use Britain’s streets and institutions to celebrate or justify violence against Jews under the alibi of “anti-Zionism”, we are no longer in the realm of ordinary protest. We are in a context where a civilian population—Jews in Britain—faces systematic rights deprivations: security at worship and schooling becomes contingent; free movement is chilled by threats near Jewish neighbourhoods; equal access to public spaces is constrained by orchestrated intimidation. The cumulative effect is a severe denial of fundamental rights—safety, assembly, worship, education—because of identity. That is persecution’s core. 

There is more. International law recognises that speech acts can themselves be international crimes when they meet specific thresholds. The Genocide Convention criminalises “direct and public incitement to commit genocide”regardless of whether genocide ensues. While not every hateful chant reaches that bar, explicitly genocidal slogans—“Gas the Jews”, “Death to the Jews”—plainly fall within its contemplation. Even where the genocidal threshold is not met, calls to violence against a protected group, broadcast at scale and coordinated with an ongoing attack on that group elsewhere, are classic indicia of a widespread or systematic attack for Article 7 purposes. The public order and terrorism statutes in the UK already criminalise stirring up religious or racial hatred and encouragement of terrorism. When such conduct is organised, identity-targeted, and persistent, and when it is linked to the aims of an armed group attacking Jews as Jews, the international law frame becomes engaged: this is not discrete “public order” offending, but a component of an attack on a civilian population. 

It will be said that crimes against humanity require a state or organisational policy. Indeed, the Elements speak of conduct “pursuant to or in furtherance of a State or organisational policy” when assessing the existence of an attack. But that is precisely the point: the organisational anchor is not hypothetical. Hamas is a proscribed terrorist organisation in UK law; its stated policy targets Jewish civilians as such. Much of the post-7 October agitation in Britain has been explicitly aligned to Hamas’s operation, lionising the very acts for which Hamas is proscribed. In that environment, systematic incitement and intimidation directed at Jews in Britain are not free-floating: they are in furtherance of the organisational policy of a group carrying out an ongoing attack against a civilian population, the overwhelming majority of whom are Jews. Where UK-based agitators knowingly contribute to this campaign of persecution—by normalising or urging violence against Jews or Israelis as Jews—they are, in legal terms, taking part in an attack directed at a civilian population. The domestic hate-crime frame is necessary but insufficient. The international crimes frame is now pertinent. 

This is not an argument for abolishing protest. It is an argument for naming the conduct for what it is when lines are crossed. Britain has ample domestic law to charge stirring up hatred and encouraging terrorism. The failure has been one of framing and will: treating a widespread, identity-targeted campaign as a series of disconnected misdemeanours. The International Criminal Court Act 2001 already incorporates crimes against humanity into UK law. Where conduct in Britain forms part of a wider, systematic attack against Jews as a civilian population, prosecutors should test the threshold of persecution alongside domestic counts. At minimum, charging language and sentencing should reflect the gravity of identity-based, organised intimidation whose purpose is to deny a minority equal enjoyment of fundamental rights. The country has already acknowledged the reality by hardening physical security around Jewish life (Reuters, 28 Feb 2024). The law should catch up with the reality it is funding. 

The practical implication is clear. Direct calls for violence against Jews and Israelis, the celebration of 7 October, and sustained intimidation around Jewish institutions are not mere offences against public order. In the present context they are components of a wider attack on a civilian population. That is the legal vocabulary of crimes against humanity. If Britain is serious about the universality of that law—and about the equality of its minorities—it should begin to act like it.
