The headlines are screaming it: Japan’s defence build-up is critical, the UK-Japan alliance is to fortify the Indo-Pacific. One might think we have stumbled into a time warp, a sepia-toned reel of 1902’s Anglo-Japanese Alliance, or perhaps a fever dream of 1941’s greater East Asia co-prosperity sphere. But no, this is 2025, and the geopolitical spectres are rattling their chains louder than ever.
Let us put aside the pieties about ‘shared democratic values’ and ‘rules-based orders’. What we are witnessing is a naked rearrangement of the global chessboard, a prelude to what the ancients called stasis, a civilisational tension that precedes great upheavals. Japan, after decades of pacifist slumber under Article 9, is awakening. Not with a gentle nudge, but with a cold shower of Chinese naval incursions and North Korean missile salvos. The UK, ever nostalgic for its imperial past, is dressing up as a global power once more, sending a carrier group east of Suez. The two are now dancing a minuet that would make Lord Palmerston blush.
Is this ‘critical’? Of course it is. But let us be honest about what this represents. It is the death rattle of the post-war liberal order. The Pax Americana is fading, and the regional powers are sharpening their claws. Japan’s defence ramp-up is not merely about deterrence; it is about identity. It is the nation grappling with its own historical demons, trying to forge a new sense of self in a world where the old taboos no longer hold. The UK, meanwhile, is a nation adrift, clinging to any alliance that recalls its faded grandeur. Together they are a study in intellectual decadence, two former empires pretending that paper treaties can hold back the tides of history.
Do not mistake my cynicism for defeatism. The alliance is rational, even necessary. The Indo-Pacific is the new Mediterranean, the sea around which tomorrow’s empires will rise and fall. But the language used its ‘critical’ nature, the urgent press releases, the solemn photo opportunities reeks of the same hubris that led Rome to believe its legions could pacify the Parthians. We are in a cycle of history where every move, every counter-move, accelerates the descent into a multipolar void. The Victorians understood this they called it the ‘Great Game’. We call it ‘security cooperation’. The substance is identical.
Let us also consider the economic insanity. Japan’s economy is stagnant, its population greying. The UK is still recovering from the self-inflicted wound of Brexit. Yet both are committing billions to defence. This is the behaviour of great powers in decline, spending on swords while the ploughs rust. Rome did this before the barbarians poured through the gates. Byzantium did this before the Crusaders sacked Constantinople. It is a pattern as old as civilisation: when the frontier feels insecure, the centre begins to cannibalise itself.
I am not suggesting we prepare for a grand war tomorrow. But we must strip away the cant. The UK-Japan alliance is a symptom, not a solution. It is a sign that the liberal international order, which we have taken for granted since 1945, is fracturing. The old certainties are gone, replaced by a volatile game of nations. To call this ‘critical’ is an understatement. It is a harbinger. The question is whether we have the wisdom to navigate these currents without repeating the mistakes of our ancestors. I suspect not. We are, after all, only human.
