Friday's attack on two mosques in New Zealand reflects a paradigm shift: the erosion of liberal values and the rise of 'civilisationalism' at the expense of the nation state.
So do broader phenomena like widespread Islamophobia with the crackdown on Turkic Muslims in Xinjiang as its extreme, and growing anti-Semitism. These phenomena are fuelled by increasing intolerance and racism enabled by the far-right and world leaders as well as ultra-conservatives and jihadists.
These world leaders and far-right ideologues couch their policies and views in terms of defending a civilisation rather than exclusively a nation state defined by its citizenry and borders.
As a result, men like China's Xi Jinping, India's Narendra Modi, Hungary's Viktor Orban and US President Donald J Trump as well as ideologues such as Steve Bannon, Mr Trump's former strategy adviser, shape an environment that legitimises violence against the “other”.
By further enabling abuse of human, minority and refugee rights, they facilitate the erosion of the norms of debate and mainstream hate speech.
Blunt and crude language employed by leaders, politicians, some media and some people of the cloth helps shape an environment in which concepts of civility and mutual respect are lost.
Consequently, the likes of Brenton Tarrant, the perpetrator of the attacks on the Christchurch mosques in which 50 people died, or Andreas Breivik, the Norwegian far-right militant who in 2011 killed 77 people in attacks on government buildings and a youth summer camp, are not simply products of prejudice.
Prejudice, often only latent, is a fact of life. It's inculcated in all cultures as well as education in schools and homes irrespective of political, religious, liberal, conservative and societal environment.
Men like Tarrant and Breivik emerge when prejudice is weaponised by a political and/or social environment that legitimises it. They are emboldened when prejudice fuses with politically and/or religiously manufactured fear, the undermining of principles of relativity, increased currency of absolutism, and the hollowing out of pluralism.
Their world is powered by the progressive abandonment of the notion of a world that is populated by a multitude of equally valid faiths, worldviews and belief systems.
The rise of civilisationalism allows men like Tarrant and Breivik, white Christian supremacists, to justify their acts of violence in civilisational terms. They believe their civilisation is under attack as a result of pluralism, diversity and migration.
The same is true for jihadists who aim to brutally establish their vision of Islamic rule at the expense not only of non-Muslim minorities but also Muslims they deem no different than infidels.
Civilisationalism provides the justification for men like Hungary's Mr Orban to adopt militant anti-migration policies and launch attacks laced with anti-Semitism on liberals like financier and philanthropist George Soros.
It also fuels China's crackdown on Turkic Muslims in the north-western province of Xinjiang, an attempt to Sinicise Islam and the most frontal assault on the Islamic faith in recent memory.
Similarly, civilisationalism validates Mr Modi's notions of India as a Hindu civilisational state and Mr Trump's anti-Muslim and anti-migrant policies and his continued vacillation between lending racism and white supremacism legitimacy and condemning far-right exclusivism.
Civilisationalism poses a threat not only to the world we live in today but also to the outcome of the geopolitical struggle of what will be the new world order. The threat goes beyond the battle for spheres of influence or competition of political systems.
Civilisationalism creates the glue for like-minded thinking, if not a tacit understanding, between men like Xi Jinping, Viktor Orban, Narendra Modi and Donald Trump, on the values that should undergird a new world order.
These men couch their policies as much in civilisationalism as in terms of defence of national interest and security.
Their embrace of civilisationalism benefits from the fact that 21st-century autocracy and authoritarianism vest survival not only in repression of dissent and denial of freedom of expression but also by maintaining at least some of the trappings of pluralism.
Those trappings can include representational bodies with no or severely limited powers, toothless opposition groups, government-controlled non-governmental organisations, and some degree of accountability.
The rise of civilisationalism is further facilitated by a failure to realise that the crisis of democracy and the revival of authoritarianism did not emerge recently but date back to the first half of 1990s.
Political scientists Anna Lührmann and Staffan I Lindberg concluded in a recently published study that some 75 countries have embraced elements of autocracy since the mid-1990s. Key countries among them have also adopted aspects of civilisationalism.
The scholars, nonetheless, struck an optimistic tone. “While this is a cause for concern, the historical perspective…shows that panic is not warranted: the current declines are relatively mild and the global share of democratic countries remains close to its all-time high,” they said.
Friday's attack in Christchurch is one of multiple civilisational writings on the wall.
So are the killings committed by Breivik; multiple jihadist attacks; the recasting of political strife in Syria and Bahrain in sectarian terms; the increasing precarity of minorities whether Muslim, Christian or Jewish; rising Buddhist nationalism; and the lack of humanitarianism and compassion towards refugees fleeing war and persecution.
These alarm bells coupled with the tacit civilisationalism-based understanding between some of the world's most powerful men brush aside the lessons of genocide in recent decades.
Ignoring the lessons of Nazi Germany, Hutu Rwanda, the Serbian siege of Srebrenica, or the Islamic State's Yazidis poses the foremost threat to a world that is based on principles of humanitarianism, compassion, live-and-let-live, and human and minority rights.
Framing the challenge, Financial Times columnist Gideon Rahman noted that Mr Trump's “predecessors confidently proclaimed that American values were 'universal' and were destined to triumph across the world. And it was the global power of western ideas that has made the nation-state the international norm for political organisation. The rise of Asian powers such as China and India may create new models: step forward, the 'civilisation state.'”
Mr Rahman argues that a civilisational state rejects human rights, propagates exclusivism and institutions that are rooted in a unique culture rather than principles of equality and universalism, and distrusts minorities and migrants because they are not part of a core civilisation.
In short, a breeding ground for strife and conflict that can only be kept in check by increasingly harsh repression and/or attempts at mass re-education and homogenisation of the “other”—ultimately a recipe for instability rather than stability and equitable progress.
