The world spent $2.2 trillion on defence last year. One year of that money could build every hospital, school, and clean water system that every developing nation needs. The arithmetic of war is always the same — destruction is fast, rebuilding is slow, and the people who pay are never the people who decided.
These numbers are not meant to be naive. Security is real. Threats are real. Nations that disarm unilaterally do not survive long enough to spend their peace dividend. The argument is not that defence spending is wrong. The argument is that the world has systematically underinvested in the infrastructure of peace — in diplomacy, in dialogue, in the patient, unglamorous work of building agreements that hold — and the cost of that underinvestment is counted in lives, not budgets.
Every bomb that falls destroys something that took decades to build. Every negotiation that succeeds creates something that can last generations. The return on investment from peace is the highest of any human activity. We have simply never treated it that way.
"Destruction is fast. Rebuilding is slow. And the people who pay are never the people who decided."
The Iran deal — if it holds — is the most significant de-escalation in West Asia in a generation. The Strait of Hormuz reopening would release $87 Brent crude pressure, ease India's import bill, and send a signal to every other conflict zone that agreements are still possible. It does not solve Iran's domestic politics, its proxy networks, or the deep mistrust that decades of sanctions and confrontation have built. But it proves the principle. Exhaustion is not defeat. Exhaustion is the beginning of diplomacy.
Palestine is different from every other conflict on this list because it has no military solution — both sides have proven this across eight decades of evidence. Every military offensive has created more fighters than it eliminated. Every civilian casualty has hardened the next generation. The solution is political, always has been, and requires two things that have been absent simultaneously: a Palestinian leadership with democratic legitimacy, and an Israeli political consensus for a two-state outcome. Neither exists today. The world's failure to create the conditions for both is not a passive failure. It is an active choice, renewed every year by every government that supplies weapons and withholds pressure.
Ukraine has paid an extraordinary price for the right to choose its own future — a right that should not require payment in blood. Russia has paid an extraordinary price for a war that has achieved the opposite of its strategic objectives — NATO stronger, Ukraine more resolute, Russia more isolated. The tragedy is that both truths can coexist and the killing continues anyway. The path to peace runs through negotiation that neither side currently believes is possible. That belief must change before the war can end. And it will only change when the cost of continuing exceeds the cost of stopping — for both sides simultaneously.
There are more people displaced by conflict in Africa today than anywhere else on earth. The Democratic Republic of Congo has been in a state of continuous armed conflict since 1996 — longer than most of the people dying in it have been alive. Sudan entered a catastrophic civil war in April 2023 that has already killed tens of thousands and displaced millions into famine conditions. Ethiopia, Somalia, Mozambique, Mali, Burkina Faso — the list of active conflicts is long and the international attention is short. These are not forgotten wars because they are unimportant. They are forgotten because the people suffering in them have no strategic value to the powers that could intervene. That is a moral verdict on the current world order — not a natural fact.
These conflicts are different in their causes, their actors, and their possible solutions. But they share one thing: every single one of them is sustained by the belief that the alternative to war is worse than war itself. The work of peace is to change that calculation — through dialogue, through pressure, through incentives, through the patient construction of agreements that make the alternative to war genuinely attractive to all parties.
It is slow. It is unglamorous. It rarely makes front pages. And it is the only thing that has ever actually worked.
In December 1914, on the Western Front, something happened that military historians still struggle to fully explain. German and British soldiers — men who had been trying to kill each other for four months — climbed out of their trenches on Christmas Eve, walked into no man's land, and played football. They exchanged cigarettes. They showed each other photographs of their families. They buried their dead together. Then, the next day, they went back to killing each other — because the orders had not changed and the war had not ended.
But for one day, the shared humanity was stronger than the ideology that said they were enemies.
In 1971, the United States and China had no diplomatic relations. They were adversaries in a Cold War that had real consequences for hundreds of millions of people. Then the American table tennis team received an unexpected invitation to visit China. What followed — Ping-Pong diplomacy — opened a channel that led to Nixon's visit to Beijing, the normalisation of relations, and one of the most consequential geopolitical shifts of the 20th century. It started with a sport.
At the 2018 Winter Olympics in PyeongChang, athletes from North and South Korea — two nations technically still at war — marched together under a unified flag. The political situation did not change that day. The missiles did not disappear. The DMZ did not open. But 100,000 people in that stadium watched two Koreas walk in together, and for that moment, a different future seemed imaginable.
The FIFA World Cup does this every four years at a scale no other human institution matches. 5 billion people watched the 2022 World Cup in Qatar. Nations that have no diplomatic relations compete on the same pitch under the same rules, officiated by the same referees, watched by the same cameras. Iran and the United States played each other. Morocco beat France — the former coloniser — and an entire continent celebrated. Argentina won and a country wept with joy. These are not political events. They are human ones. And that is precisely their power.
The Olympics carry the same force. The truce that the ancient Greeks observed during the Olympic Games — the ekecheiria — suspended all wars to allow athletes and spectators to travel safely. The world has not managed to revive that truce in its modern form. But the aspiration exists. The IOC formally calls for an Olympic Truce before every Games. Governments sign it. The wars continue anyway. But the aspiration — the refusal to accept that competition must mean conflict — is itself worth defending.
We raise this not as naivety. The World Cup does not end wars. The Olympics did not stop Russia invading Ukraine. Sport is not a substitute for politics, and politics is not a substitute for justice. But the FIFA World Cup and the Olympics do something that governments, armies, and sanctions cannot: they remind billions of people simultaneously that humans from every nation, every religion, every history, can share a field, follow the same rules, and find the result meaningful — without anyone dying.
That reminder matters. It is not nothing. In a world that has normalised the idea that conflict between nations is inevitable, that reminder is an act of resistance.
We do not rest till we do our best. The wars in Palestine, Ukraine, Sudan, and the Congo are not natural disasters. They are human decisions — and human decisions can be unmade. Dialogue and diplomacy must take precedent over bombs. Not because they are easy. Not because they always succeed. But because the alternative is a world that burns faster than it builds — and we have seen enough of that world already.
