History does not repeat, but it often rhymes. And the rhyming couplet currently echoing through Whitehall is a stark one: the return of Donald Trump to the White House, and the emergence of a China that is not just assertive but positively imperial. The UK Foreign Office, that venerable institution of fudged compromises and gentlemanly gestures, is scrambling to recalibrate a strategy that was predicated on the assumption that American power was a renewable resource. It is not. The dragon has been fed, and it has grown scales of steel.

Let us be clear: the China that Trump faced in 2016 was a China still playing by the rules of the globalist order, albeit with a smirk. The China of 2025 is a China that has watched the West descend into intellectual decadence, its elites obsessed with identity politics while Beijing builds ports, patents, and particle colliders. The Belt and Road Initiative is no longer a vague infrastructure fantasy: it is a vast network of dependencies that stretches from the South China Sea to the Baltic. The UK, once the master of such imperial architecture, now finds itself a supplicant in a project it cannot join.

Trump, for all his bluster, is a transaction a realist. He understands power in terms of tariffs and tweets. But China understands power in terms of millennia. The British foreign office mandarins, with their careful briefing notes and their love of the word 'nuanced', are ill equipped to negotiate with a civilisation that views a hundred years as a short term. They speak of 'recalibration' as if it were a matter of adjusting a telescope. It is not. It is a matter of recognising that the West no longer holds the monopoly on historical destiny.

The tragedy is that the UK could have been a broker between the two titans. Instead, it has become a client state of Washington, signing defence pacts and intelligence sharing agreements that tie its hands. The five eyes? They are now the two eyes of America and the myopic gaze of its satellites. When the US and China resume their cold war of tariffs and technology bans, the UK will be dragged along, regardless of its own commercial interests. The City of London, that great engine of global finance, will be collateral damage in a war it cannot win.

But let us not be entirely bleak. There is a lesson here for those who care to learn it. The Victorians understood that empire required both might and right, a sense of mission that legitimated power. The modern West has abandoned the 'right' in favour of a shallow moralism, and the 'might' has been frittered away on wars of choice and regulatory navel gazing. China, for all its authoritarianism, has a clear sense of purpose: it is restoring its rightful place at the centre of the world. Whether one likes that or not is irrelevant. It is the reality.

So what should the UK do? Not lecture, for a start. Not moralise about human rights while selling arms to the Saudis. The first step is to recognise that we are no longer the global policeman, nor even the global moraliser. We are a mid sized power with a historical talent for commercial diplomacy. We need to carve out a niche that does not depend on American patronage or Chinese forbearance. That means investing in our own technological sovereignty, rebuilding our industrial base, and perhaps even cultivating a little old fashioned cynicism about the intentions of both superpowers.

Trump's return may be a calamity or a catharsis. But it is not a surprise. China's strength is not a surprise either. What would be a surprise is if the UK Foreign Office actually woke up from its dogmatic slumbers and realised that the world has moved on. We no longer live in the era of liberal internationalism. We live in the era of competitive realism. It is time to act accordingly.
