(CNN) Terrorism is an increasingly globalized phenomenon. The 28-year old terror suspect behind the shooting in cold blood of 49 Muslim worshipers at two mosques in Christchurch, New Zealand, is an Australian who identifies as European, and who cites the leadership of London's Sadiq Khan, Germany's Angela Merkel and Turkey's Recep Tayyip Erdogan as part of his perverse justification for his violence.

His ideology is rooted in a grand narrative of Western culture in decline, a global picture of perceived Islamic conquest of Christian lands, and a belief in the genocide of the "European people" across the world.

The killer's "manifesto," which lays out a warped rationale for his brutal attack, encapsulates a fundamental irony, presenting a transnational version of extremist nationalism. It chimes with a modern far right that is increasingly characterized by growing internationalism and consolidation, with violent extremists framing their struggle as transcending national borders, including fighting against a common Muslim enemy in defense of a Christian West.

Where ethno-nationalism was previously characterized by petty squabbles between competing irredentist visions, the suspected Christchurch shooter, who CNN is currently not naming, calls for international solidarity between extremists in Poland, Austria, France, Argentina, Australia, Canada or even Venezuela, brought together through the online space. This has created a new hybrid of disparate extremist ideologies -- in this case a mixture of eco-fascism, national socialism and white supremacy -- which sits within a global framing.

It is not only the shooter's ideology that is global, but also his roster of influences. In the manifesto, the shooter fondly references fellow extremists from around the world, including Luca Traini, who injured six migrants in a shooting in Italy; Dylann Roof, the Charleston church shooter who killed nine African Americans; Anton Lundin Pettersson, a Swede who attacked a school with a sword; and Darren Osbourne, who carried out the Finsbury Park mosque attack, as inspirations behind his violent radicalization. Anders Behring Breivik is singled out for adoration, and the shooter says they had the online blessing of the Knights Templar Far Right group, with which Breivik associated himself in his own manifesto eight years ago before killing 77 people.
