In a recent opinion piece in The Australian conservative British historian and US resident Niall Ferguson reflects on the legacy of 9/11 and concludes – after two decades of analysis – that the attacks on 11 September 2001 signaled not merely terrorism but a broader clash of civilisations that the West is now losing. Recalling his own reactions on that momentous day, Ferguson admits that he initially sought secular explanations for the attacks: economic downturns, American imperial overreach, and global political fragmentation. Yet re-examining Osama bin Laden’s statements, he recognises that the al-Qa’ida leader framed his actions as a religious war against “crusaders,” rooted in Islamic grievance over Palestine and Western dominance. Bin Laden’s explicit appeal to faith, not politics, aligns with Samuel Huntington’s much-criticised thesis that post–Cold War conflict would be cultural, with Islam and the West as enduring antagonists.
Although the United States and its allies largely defeated jihadist terrorism within their own borders—terrorism in Iraq has plummeted and attacks in the U.S. remain rare—Ferguson argues that Islamism has advanced through dawa (non-violent proselytising) and political penetration. Organisations such as the Council on American-Islamic Relations, linked to the Muslim Brotherhood, exploit Western legal and educational institutions while Gulf states like Qatar fund universities and shape intellectual climates. Meanwhile, demographic trends favour Islam: global Muslim populations are rising rapidly and will nearly equal Christians by mid-century, while Western societies grow more secular and internally divided.
Geopolitically, the West faces a resurgent “axis of upheaval”—China, Russia, Iran, and North Korea—while allies waver. The international solidarity that followed 9/11 contrasts sharply with the fragmented reaction to Hamas’s October 7, 2023 attacks on Israel, where UN resolutions condemned Israeli actions more than Islamist violence and several states recognised Palestinian statehood. Public opinion, especially among younger generations, has shifted sharply against Israel and, in some cases, towards open antisemitism; bin Laden’s anti-Western rhetoric even circulates approvingly on platforms like TikTok.
Ferguson concedes that bin Laden lost the “war on terror,” but claims he is winning the longer contest Huntington foresaw. Islamism thrives without spectacular violence, demographic momentum favours Muslim societies, and Western civilisation—once confident in its Judeo-Christian identity—is fractured and uncertain. Two decades after 9/11, Ferguson concludes that the clash of civilisations is real, and the West is no longer clearly ahead.

Osama bin Laden’s Posthumous Victory
On the day of the attacks, I sat in my study at Jesus College, Oxford, staring incredulously at the pixelated live video of the World Trade Centre twin towers first blazing, then collapsing. Not long after, in April 2002, I accepted a chair at the Stern School of Business at New York University and resigned my Oxford professorship.
My motivation was partly the hereditary Scottish tendency to march towards the sound of gunfire. As a teenager in 1914, my grandfather John Ferguson had volunteered to fight the Germans. This seemed easier.
Regardless of the 9/11 attackers’ motives, I had a strong objection to terrorism as a political method – a result of growing up in Glasgow in the 1970s, when “the Troubles” in nearby Northern Ireland did more than merely resonate.
My first impulse after the attacks, in a piece for The New York Times, was to liken the sympathetic British reaction to 9/11 to the American reaction to the Blitz of 1940-41.

But I also warned Americans to “steel themselves for a long, inglorious kind of war that governments in Europe already know only too well”. In wars against terrorists, I wrote, “there are no quick victories. The foe does not line up his tanks for you to flatten, his ships for you to sink. His troops live among you.”
Yet this was not the Provisional IRA. Re-reading a transcript of Osama bin Laden’s first post-9/11 video, from November 3, 2001, I am reminded of how explicitly he declared a war of religion. “People were divided into two parts” after 9/11, he declared. “The first part supported these strikes against US tyranny, while the second denounced them.
“The vast majority of the sons of the Islamic world were happy about these strikes,” bin Laden went on, “because they believe that the strikes were in reaction to the huge criminality practised by Israel and the United States in Palestine and other Muslim countries.”
Al-Qaeda mastermind Osama bin Laden.
There were demonstrations of support for his action “from the farthest point in the eastern part of the Islamic world to the farthest point in the western part of the Islamic world”. This revealed the key reality: “This war is fundamentally religious. The people of the East are Muslims. They sympathised with Muslims against the people of the West, who are the crusaders.”
With the passage of 2½ decades, it is startling just how unambiguous bin Laden was about his religious motive. “Under no circumstances,” he declared, “should we forget this enmity between us and the infidels. For the enmity is based on creed … It is a question of faith, not a war against terrorism.” The goal of all Muslims should now be to “resist the most ferocious, serious and violent Crusade campaign against Islam ever since the message was revealed” to Mohammed.
Bin Laden saw the war he was waging as a counter-attack – “to take revenge for those innocent children in Palestine, Iraq, southern Sudan, Somalia, Kashmir and The Philippines”. The US president, George W. Bush, might be the latest “crusader”, who “carried the cross and raised its banner high”, but bin Laden traced his war back to the aftermath of World War I when “the whole Islamic world fell under the crusader banner … and Palestine was occupied by the British”. Now the tables had been turned. And he had turned them with just 19 men whose faith exalted martyrdom.

You can see why, at the time, many commentators saw 9/11 as vindicating Harvard political scientist Samuel Huntington, whose seminal essay on The Clash of Civilisations had been published in 1993, as well as Princeton scholar Bernard Lewis, who had long argued that Islam was chronically unable to modernise.
My wife, Ayaan Hirsi Ali, was born in Somalia and shared this view, not because she was a scholar of Islam but because she was a Muslim – and, indeed, a former member of the Muslim Brotherhood. In September 2001, she was working at a political think tank in the Netherlands, having sought asylum there in 1992 to escape war-torn Mogadishu and an arranged marriage.

In her memoir, Infidel, she recalls how, after hearing bin Laden’s video, she “picked up the (Koran) and the hadith and started looking through them, to check. I hated to do it, because I knew that I would find bin Laden’s quotations in there.” She shot to notoriety by telling the Dutch that the 9/11 attackers were simply following the Prophet Mohammed’s injunction to wage holy war.
Over the past 24 years I have valiantly tried to see 9/11 differently – not as a civilisational clash between Islam and “the West” but as something that fit better into my own secular frame of reference. Raised an atheist, trained as an economic historian, I felt obliged to look behind what I took to be the facade of religious zealotry.
A decade after the attacks, in a piece I wrote for The New York Times Magazine, I portrayed them as the product of four underlying historical trends. First, the spread of terrorism from the Middle East and Europe to the US. Second, the post-2000 economic downturn, combined with widening inequality between nations and a coming oil shock, possibly compounded by a Saudi revolution akin to the one that overthrew the shah in Iran in 1979. (I completely failed to foresee the shale oil revolution and bought into the “peak oil” myth.) Third, the transition of American global power from informal to formal imperialism. And last, the fragmentation of the multicultural polity. (“Rather than anticipating a clash between monolithic civilisations, we should expect a continued process of political disintegration as religious and ethnic conflicts challenge the integrity of existing multicultural nation-states.”)
Missing in this – and in much of my work that followed – was Islam.
In The War of the World (2006), I got a little closer to Huntington, portraying 1979 as a much bigger turning point than 2001 in terms of the demographic as well as political rise of Islam, a point I returned to in Civilization: The West and the Rest (2011). However, laboriously quantifying every war since Huntington’s essay had appeared, I argued that most conflicts since 1993 had, in reality, been within rather than between civilisations. In The Square and the Tower (2017), I applied network theory to the problem, showing how al-Qaeda itself was a network within a much larger network of Islamist organisations; and that its expansion in response to the invasion of Iraq ultimately necessitated a networked response (in the form of General Stan McChrystal’s Joint Special Operations Command). Most recently, in Doom (2021), I downgraded 9/11 to just another disaster, and not a very big one: “In terms of excess mortality, April 2020 in New York City was … three and a half times worse than September 2001, the month of the 9/11 terrorist attack.”
Huntington, Lewis and my wife were right.
In Huntington’s original formulation, “the fundamental source of conflict” in the world after the Cold War would be cultural; “the principal conflicts of global politics” would be “between nations and groups of different civilisations” – “Western, Confucian, Japanese, Islamic, Hindu, Slavic-Orthodox, Latin American, and possibly African”. In particular, Huntington predicted, the “centuries-old military interaction between the West and Islam” could become “more virulent”. He also foresaw a “Confucian-Islamic military connection” that would culminate in a conflict between “The West and the Rest”.
Among the younger generation of proto-woke Ivy League professors, Huntington was widely mocked for his “essentialism”. But consider, with Huntington’s argument in mind, all that has happened since September 2001.
Terrorism has largely been contained in the US and EU, though not globally. In that sense, we won the “war on terror”, which was successfully displaced from the US to the periphery. It was ultimately defeated in Iraq, though not in Afghanistan. Today, as a result, terrorism in the world looks very different from what I foresaw in 2001. According to the Global Terrorism Index 2025, published by the Institute for Economics & Peace, the top five countries most impacted by terrorism last year were: Burkina Faso, Pakistan, Syria, Mali and Niger. Globally, terrorism peaked in 2014-15. In countries such as Iraq, it has declined dramatically. (In 2007, terrorists claimed 6249 lives in Iraq. Last year, the total was just 59.)
In the US, it is widely asserted, white supremacists now pose a bigger terrorist threat than Islamists – although the attack in New Orleans on January 1, 2025, when Shamsud-Din Jabbar killed 14 people by driving a pick-up truck into a crowd on Bourbon Street, is a reminder that Islamic State has not entirely gone away. We now know who murdered Charlie Kirk, and a white supremacist he was not.
Still, the latest Global Terrorism Threat Assessment by the Centre for Strategic and International Studies makes clear just how wrong I was in 2001 to anticipate a sustained campaign of jihadist terrorism in the US. Say what you like about our national security agencies, they won that war.
Yet nonviolent radicalisation (what Islam calls dawa as opposed to violent jihad) has advanced significantly everywhere in the Western world, wherever there are Muslim communities. The critical point – as my wife explained in a book on the subject – is that Islamism as a deeply illiberal political ideology does not need to engage in acts of terrorism to spread.
I never cease to marvel at the ingenuity with which the Muslim Brotherhood and other proselytising organisations spread their networks, through mosques, Islamic centres, schools, colleges and local politics. Consider only the effectiveness of the Council of American-Islamic Relations, founded in 1994, which today boasts on its website of having “100+ active lawsuits” and “600,000+ Legislative Action Alerts”, whatever that means. It has almost 30 offices throughout the country.
Most people who encounter CAIR take it to be something like the Anti-Defamation League for Muslims – a civil rights organisation that just happens to be concerned about the rights of Muslims. But it is not that at all.

Rather, it is more like a front organisation for the Muslim Brotherhood of America. In a recent article, Ayaan has brilliantly described the many ingenious ways that CAIR exploits the institutions of our open society, most recently settling a lawsuit to avoid revealing its sources of funding.
Good luck following the money. In her words: “The North American Islamic Trust (NAIT) controls mosque properties and financial assets. The Islamic Society of North America (ISNA) lends the Brotherhood a degree of religious legitimacy. The American Muslim Council (AMC) works the political front, cutting deals and building alliances. The Muslim American Society (MAS) runs operations on the ground, embedding itself firmly in local communities. In universities, the International Institute of Islamic Thought (IIIT) shapes the narrative. On campuses, the Muslim Students’ Association (MSA) targets the next wave of recruits. The Islamic Circle of North America (ICNA) and Young Muslims (YM) focus on families and youth.”
Even the United Arab Emirates has proscribed CAIR as a terrorist organisation. Yet dozens of Democratic legislators are on the record on the CAIR website, praising its work as they doubtless also praise the National Association for the Advancement of Colored People.
A complementary effort is the way Qatar – the largest source of foreign donations to US universities since reporting began in 1986 – funnels money into academia. According to the Network Contagion Research Institute, as reported in The Free Press, nearly a third of Qatari donations to American colleges – more than $US2bn – were given between 2021 and 2024. As Mitchell G. Bard shows in Arab Funding of American Universities (2025), this money is one of the reasons college campuses have become such hotbeds of anti-Semitism in recent years.
It is not just that the West has been successfully penetrated by an antagonistic civilisation that fundamentally rejects the fundamental division between religion and politics – church and state – that lies at the heart of both Christianity and Judaism. The West is also being geopolitically outmanoeuvred by “the rest” in just the way Huntington foresaw.

Contrast the global order after 9/11 with the global order today. We have come a long way since NATO secretary-general George Robertson’s statement on September 11, 2001: “Our message to the people of the United States is … ‘We are with you’.”
In the past three years, Zbig Brzezinski’s worst-case scenario has come about. “Potentially, the most dangerous scenario,” he wrote in The Grand Chessboard (1997), “would be a grand coalition of China, Russia, and perhaps Iran, an ‘antihegemonic’ coalition united not by ideology but by complementary grievances”.
Since the Russian invasion of Ukraine, that grand coalition has come into being, with North Korea as a fourth member. The “axis of upheaval” (China, Russia, Iran, and North Korea) is now co-operating in military, economic and diplomatic ways.
Moreover, the Trump administration’s combative treatment of US allies (the EU, Japan, South Korea) and neutrals (Brazil, India and Switzerland), not least with respect to trade policy, is alienating not only the traditionally non-aligned but also key partners.
The upshot is that Israel is now virtually alone in fighting against the Islamists, so that even the US wants plausible deniability when, as earlier this month, the Israeli Air Force strikes the leadership of Hamas in the Qatari capital, Doha.
The point is that the clash of civilisation continues. Now ask yourself: Who’s winning?
The Hamas attack on Israel two years ago was essentially an Israeli 9/11 (worse in relative terms). But compare the global reactions.
UN Security Council Resolution 1373, adopted unanimously on September 28, 2001, called on all member states to freeze terrorist financing, pass anti-terrorism laws, prevent suspected terrorists from travelling across international borders, and screen asylum-seekers for possible terrorist ties. This was an unprecedented show of international unity.
By contrast, no Security Council resolution could be passed in the wake of October 7. UN General Assembly Resolution ES-10/21 – which called for an “immediate” and “sustained” humanitarian truce and “cessation of hostilities” in Gaza and condemned “all acts of violence aimed at Palestinian and Israeli civilians” – was introduced by Jordan on behalf of a group of Arab states. When it was adopted on October 27, 2023, 121 voted in favour, 44 abstained, 14 absented themselves and only 14 (including Israel and the US) voted against.

Ten countries have recognised the non-existent Palestinian state since October 7, including three EU member states, Ireland, Slovenia, and Spain. Canada, France, Australia and Britain are itching to join them.
In short, comparing the world today with that of 24 years ago, I am tempted to say bin Laden lost the war on terror but is winning the clash of civilisations. That’s not to say his particular brand of Salafist jihadism is winning; it can even be argued that it’s in decline. Bin Laden’s creed was always too uncompromising to form alliances of convenience. By contrast, the pro-Palestinian “global intifada” is much more omnivorous, and can easily absorb the old left (Marxism and pan-Arabism) and the new (anti-globalism and wokeism).
Demographically, Islam is certainly winning. According to Pew Research (June 2025), “The number of Muslims around the world grew 21 per cent between 2010 and 2020, from 1.7 billion to 2.0 billion.” That was twice as fast as the rest of the world’s population, increasing the Muslim share from 24 per cent to 26 per cent. Earlier research by Pew (from 2015) forecast that “if current trends continue, by 2050 the number of Muslims will nearly equal the number of Christians around the world”. In Europe, Pew estimated, Muslims would make up 10 per cent of the overall population, up from 5.9 per cent in 2010. In the US, Muslims would outnumber Jews. This does not seem implausible.
At the same time, Western civilisation today is so much more divided than it was 24 years ago. The public response to October 7 illuminated the divisions. Whereas older voters generally remain more pro-Israel than pro-Palestinian, younger cohorts have swung the other way. Perhaps that’s because to Gen Z, September 11 is a faint memory – as distant as the Cuban missile crisis and John F. Kennedy’s assassination were to my generation. But it’s also because the Islamists have done such a good job of co-opting the campus radicals, somehow overriding the cognitive dissonance in slogans such as “Queers for Palestine”, while tapping the anti-Semitism that still lurks on the far right.
According to Brookings, “young Republicans aged 18-49 have shifted from 35 per cent having an unfavourable view of Israel to 50 per cent unfavourable … Among Democrats, there has been an increase of 62 per cent to 71 per cent (with an unfavourable view of Israel) in the 18 to 49-year-old demographic … Only 9 per cent of those aged 18 to 34 approve of Israel’s military actions in Gaza.”

A recent poll in Britain by Campaign Against Anti-Semitism revealed a striking shift in attitudes towards Jews. Once again, the swing towards anti-Semitism is more pronounced among the young: “Forty-five per cent of the British public … believes that Israel treats the Palestinians like the Nazis treated the Jews … 60 per cent of young people believe this.
“Forty-nine per cent of 18-24-year-olds are uncomfortable spending time with people who openly support Israel.
“Only 31 per cent of young voters agree that Israel has a right to exist as a homeland for the Jewish people.
“Twenty-six per cent of the British public believes that Israel can get away with anything because its supporters control the media.
“Nineteen per cent of young people believe that the Hamas attack on Israel was justified.”
Such attitudes can be found in Britain on both the political left and the political right. A third of Labour voters say they are uncomfortable spending time with people who openly support Israel, as do 54 per cent of Green Party voters, 15 per cent of whom believe Hamas’s attack on Israel was justified. But almost one in four supporters of the rapidly growing Reform UK party, led by Nigel Farage, believe Jewish people “chase money more than other people do”.
During the Cold War, the West was often referred to as a “Judaeo-Christian” civilisation. That term is starting to seem like an anachronism. Two years ago, another bin Laden pronouncement – his Letter to America, originally published on the first anniversary of September 11 – enjoyed a sudden resurgence of interest, not least because its attacks on the power of American Jews seemed to strike a chord with young users of TikTok.

One popular video showed a young woman brushing her hair with the caption, “When you read Osama bin Laden’s letter to America and you realise you’ve been lied to your whole entire life.” At one point in November 2023, a TikTok search for #lettertoamerica found videos with 14.2 million views. In total, about 300 videos were posted under that hashtag.
Walking the streets of New York last week, I felt old. To my children, my students and my employees, September 11 is not a memory. It is not even a historical fact. It is something people argue about on social media.
As I write, Tucker Carlson has just told Piers Morgan that an “FBI document” indicated “an Israeli spy ring in the United States … knew 9/11 was coming”. The reality is, of course, that only the conspirators themselves knew that. They also knew, very clearly, why they were going to do it.
It has taken me all these years to understand that 9/11 really was a clash of civilisations. And it has taken me until now finally to face the reality that ours is losing.
