Longest period without nuclear explosion since beginning of atomic age

January 14 marked a date that, although it passed almost unnoticed, says a lot about the world we live in today. After all, for 8 years, 4 months and 29 days, no nuclear weapon has been detonated on Earth. It's the longest period without a nuclear detonation since the beginning of the atomic age, an absolute record unmatched since 1945.

This is a silence that weighs heavily on the concience but at the same time is significant. It has to do with progress, diplomacy, fears that never really went away and a fragile but real hope. To understand the significance of this milestone, we must go back in time. Everything begins in 1945, when the first nuclear test in history is conducted in the desert of the southwestern United States. From that moment on, the planet officially entered the atomic age.

Since then, the numbers have been staggering: about 2,000 nuclear weapons have been detonated by eight different countries. A huge number, when you consider the devastating environmental and health effects that many of these tests have left, often on populations that had no choice.

In particular, in the early decades of the Cold War, explosions were commonplace. Some years saw more than a hundred nuclear tests, resulting in a frenzied acceleration of the arms race. It was an era when the planet was treated like a giant open-air laboratory, with no regard for air, water, soil or human health.

From 2017 to today, a nuclear quiet we have never known before

The 'quiet' period in which we now find ourselves has a precise start date: September 2017, when North Korea conducted its last nuclear test. Since then, no other nuclear-armed country has detonated a nuclear payload.

All other nuclear states had already stopped testing between 1990 and 1998, the year Pakistan also ended its test program. From then on, the world slowly began to change course.

A key role was played by the Comprehensive Test Ban Treaty (CTBT), which was opened for signature in 1996. Today, it has been signed by 187 countries and ratified by 178: an overwhelming majority that has helped create one of the strongest taboos in contemporary international politics.

Those who violate this ban are immediately isolated, labeled as pariah states and excluded from much of diplomatic relations. Even countries that have not formally ratified the treaty, such as the United States, nevertheless continue to abide by the stop on nuclear testing, knowing that the image and political damage would far outweigh any technical or military benefits.

A record to celebrate, without forgetting that the nuclear risk has not disappeared

Looking at this long period without detonations with enthusiasm is justified, but at the same time realism is needed. The nuclear threat has not disappeared. During the Cold War, and on several occasions, the world was within a hair's breadth from the abyss, and was separated from nuclear war solely by a malfunction, a human error or a decision that had to be made within seconds by someone under enormous pressure.

We are still not that far away from those scenarios. The geopolitical tensions are still there, as are the nuclear arsenals. And yet this record also tells us something else: it proves that change is possible.

Every day that passes without a detonation is an extra day without new radioactive contamination, without sacrificed areas, without populations exposed to devastating health effects that last for generations. It's a small, quiet step forward for the health of our planet and everyone who lives on it.

And perhaps that's precisely the most important message: each new day without atomic explosions is one more reason to hope that, as has happened in the past, common sense and responsibility will once again prevail. The record can continue to grow. It also depends on us, as a global community, not to break this fragile silence.
