The world endured 65 armed conflicts in 2025, the highest number since record-keeping began in 1946, according to the Uppsala Conflict Data Program (UCDP) in Sweden. The tally includes a doubling of interstate wars to eight—the most since the Second World War—with hot spots ranging from the Russia-Ukraine war to Iran-Israel hostilities and the India-Pakistan front. Therese Pettersson, a researcher at UCDP, described the trend as “deeply worrying,” noting that the year was also the bloodiest in over three decades. Viewed from Stockholm, where the data is compiled, the escalation suggests a fundamental unraveling of the post-war security architecture.

The Global Peace Index 2026, published by the Institute for Economics and Peace, lends grim reinforcement. The average level of global peacefulness deteriorated by 0.7 per cent over the previous year, marking twelve consecutive years of retreat. Though Iceland remains the world’s most peaceful country for the nineteenth year running, the report warns of a widening gulf: 99 countries worsened their scores while only 62 improved. Analysts in London note that the divergence is propelled not just by active wars but by rising militarisation and domestic instability, creating a self-reinforcing cycle of insecurity.

Yet, against this backdrop, a different measure offers a counterpoint. The Happy Cities Index 2026, produced by a London- and Paris-based institute, crowns Nordic and European urban centres as places where well-being flourishes. The index, which assesses cities of more than 100,000 inhabitants on criteria such as urban balance, sustainability, and service efficiency, found that design for real quality of life—rather than economic muscle alone—yields happier citizens. Copenhagen, Stockholm, and Helsinki feature prominently, suggesting that pockets of tranquillity persist even as global conflict spreads.

The contrast is instructive. For all the bloodshed on interstate battlefields, happiness in these cities is not merely a luxury but a testament to resilient public policy. The happiness researchers point to a formula of green spaces, reliable public transport, and social cohesion—elements largely absent from war-torn regions. Viewed from Brussels or Berlin, the message is that the very governance that fosters urban contentment is being tested by geopolitical fractures that threaten to spill over borders.

The UCDP’s data, analysed in Washington, reinforces fears that the international rules-based order is under historic strain. With great powers locked in proxy and direct confrontations, the prospect of a broader conflagration cannot be dismissed. Yet the Happy Cities findings hint at what is at stake: the ability of ordinary citizens to live without fear. Whether this duality can hold—or whether the spreading conflict will eventually corrode even the most serene capitals—is the pressing question of our time.
