After 1945, the Soviet Union became the main propagator of anti-Israel sentiment, blending it with anti-Western narratives. The USSR’s portrayal of Zionism as ‘racism’ reached global audiences through sympathetic governments and media in the Non-Aligned Movement. This framing influenced United Nations General Assembly Resolution 3379 (1975), which equated Zionism with racism—a resolution supported by Arab states, the Soviet bloc, and many African countries, and repealed only in 1991.

The Palestinian cause thus became a universal screen onto which everyone projected their own agendas. For the far right, it offered a contemporary vehicle for age-old conspiracy theories about Jewish control. For the far left, it became the emblem of anti-colonial and anti-capitalist struggle. For Islamists, it was—and remains—a war given divine sanction.

A United Front

In European capitals, far-right, far-left, and Islamist groups have been observed marching side by side under the ‘Free Palestine’ banner. Placards and chants blend left-wing accusations of ‘apartheid’ with Islamist war cries like ‘Khaybar, Khaybar, ya Yahud’—a historical reference to the 7th-century battle in which a Jewish community was defeated by early Muslims. Some rallies feature imagery recycled from Nazi-era caricatures alongside modern anti-Israel propaganda.

The same pattern emerges in international politics. At the United Nations Human Rights Council, authoritarian regimes, left-wing populist governments, and Islamic republics often vote in unison for resolutions censuring Israel, with scant reference to the conduct of Hamas, Hezbollah, or other hostile actors. This coalition is tactical rather than ideological—united only by its shared target.

More Hands, Wider Reach

The alliance is not a coincidence. The far right borrows the lexicon of the far left and Islamists to repackage antisemitism as ‘anti-globalism’ or ‘anti-elitism’. The far left integrates Islamist narratives to fortify its critique of Western imperialism. Islamists exploit leftist solidarity rhetoric to cultivate allies in Western civil society, particularly within student movements and NGOs.

This ideological cross-pollination creates a multi-front threat. Jewish life in Europe, North America, and parts of Latin America now faces overlapping dangers: physical assaults on individuals, vandalism of synagogues, harassment on university campuses, and orchestrated online smear campaigns. 

Analysis by the Institute for Strategic Dialogue (ISD) and CASM Technology found that the weekly average of antisemitic tweets on X (formerly Twitter) increased by 105% in the six months following the platform’s change in ownership in late 2022. Elon Musk, the platform’s owner, has rejected claims that antisemitism on X reflects his intentions or personal beliefs, calling such accusations ‘false’ and asserting that ‘nothing could be further from the truth’. He argues that these criticisms stem from what he views as coordinated pressure campaigns by advocacy groups, which he says have harmed X’s advertising revenue and public image.

Digital Networks: The Modern Amplifier

Social media has now become the critical force multiplier for this alliance. Islamist propaganda channels, far-left activist accounts, and far-right conspiracy networks often share and reinforce each other’s content—sometimes without direct coordination, but with clear thematic overlap. Hashtags like #FreePalestine, #Globalists, and #BoycottIsrael circulate simultaneously in Arabic, English, and European languages, allowing narratives to jump linguistic and ideological boundaries in real time.

Encrypted platforms such as Telegram further enable coordination across borders, from neo-Nazi cells in Eastern Europe to Islamist networks in North Africa. The rapid adaptation of memes and videos allows the same antisemitic tropes to appear in left-wing protest feeds, far-right forums, and Islamist propaganda outlets within hours.

Urgent Steps to Counter the Alliance

The red line is clear: criticism of Israel is legitimate, but it turns into antisemitism once it slips into demonisation, delegitimisation, or denial of the state’s right to exist. Blurring this distinction opens the door to hate—and that is precisely what is happening all too often in politics and the media today.

Education is the first line of defence. Only those who understand the continuities between Nazi propaganda, Soviet anti-Zionism, and today’s recycled ‘anti-Zionist’ slogans can expose the patterns and disguises that resurface decade after decade. This historical literacy must be embedded in school curricula. Political consistency is just as vital. NGOs, political parties, churches, and mosques cannot afford double standards. Antisemitism is not a ‘minor issue’ to be excused when it comes from allies. Here, non-negotiable red lines must be drawn—without exceptions.

Above all, protecting Jewish life is not a favour but a duty of the state. Synagogues, schools, and cultural centres require security—backed by funding, intelligence-sharing, and strong legal enforcement. To economise here is to economise on democracy itself. And then there is the digital battlefield. Antisemitism has migrated online, where it fuels radicalisation and violence. Governments and civil society must respond with counter-narrative campaigns, AI-driven detection, and uncompromising cooperation with tech platforms. Leaving this space to the haters means abandoning it to extremism.

The alliance against antisemitism cannot remain a slogan. It must begin in the classroom, show resolve in politics, guarantee safety in daily life, and demonstrate force online. Only then can Europe credibly prove that it has learned the lessons of history.

A Test of Democratic Resilience

Antisemitism is more than a prejudice; it is a measure of a society’s democratic health. When tolerated, it corrodes trust in institutions, fuels extremism, and normalises political violence. The far-right, far-left, and Arab-Islamist cross-front illustrates how hate adapts, moving fluidly across political, religious, and cultural lines.

The test is not merely whether democracies can protect Jewish citizens—though that is paramount—but whether they can uphold the rule of law, maintain political coherence, and defend the principles of an open society against a coalition that thrives on polarisation.

Statement

The alliance between far-right, far-left, and Arab-Islamist antisemitism is no historical accident but the product of decades of ideological cross-pollination, fuelled by propaganda, opportunism, and digital amplification. This coalition threatens not only Jewish life but also the credibility of Western democracies themselves. To confront it, policymakers, educators, and civil society leaders must name it plainly, expose it with evidence, and isolate it. Failure to act risks normalising a prejudice that has, in history, always been the harbinger of wider democratic decay. Antisemitism is an assault on the open society itself—defeating it is a test we cannot afford to fail.
