The most disturbing thing about the latest hint that Yemen may possess chemical-weapons stockpiles is not necessarily what may be hidden in Yemen. It is what the allegation forces us to ask about everywhere else.
Chemical weapons were supposed to belong to history's darkest museum: mustard gas in the trenches, nerve agents in Cold War bunkers, photographs of terrified civilians fleeing invisible clouds. The world built treaties, inspectors and elaborate systems of verification precisely because civilization had decided that poison gas was a line that civilized states would not cross.
Yet here we are, in another Middle Eastern war, wondering whether chemical weapons may still be sitting somewhere in warehouses, military compounds or forgotten bunkers.
Yemen is particularly alarming because war has a habit of turning inventories into mysteries. Governments collapse. Command structures fragment. Military installations change hands. Records disappear. Intelligence becomes contradictory. Weapons once controlled by a state can become controlled by nobody or by everybody.
That is the nightmare. The international chemical-weapons regime has achieved something extraordinary. The declared stockpiles of states belonging to the global convention have been destroyed under international verification. But "declared" is doing a great deal of work in that sentence. The system depends upon states telling the truth, inspectors gaining access and governments retaining enough institutional stability to know what they possess.
War is exceptionally good at destroying all three assumptions. And Yemen is hardly alone in living at the intersection of civil conflict, regional intervention, clandestine weapons networks and collapsing state authority. Syria demonstrated how quickly chemical warfare could return from the historical basement. The recent discovery of remnants of the Assad-era programme should have reminded the world that destroying a declared arsenal is not necessarily the same thing as discovering every weapon, every precursor, every laboratory or every buried secret.
The uncomfortable question, therefore, is not simply: Does Yemen have chemical weapons? It is: How many Yemens are there?
How many countries have weapons nobody has officially declared? How many arsenals are poorly documented? How many governments possess suspicious industrial chemicals that could be diverted during a collapse? How many military depots are sitting in countries where nobody can confidently say who controls them six months from now?
The answer should concern us more than another round of diplomatic finger-pointing. Chemical weapons are particularly dangerous because their proliferation does not require a superpower. A government with a functioning bureaucracy can build an elaborate programme. A collapsing government can inherit one. A militia can seize pieces of one. A terrorist organization does not necessarily need a vast industrial complex if it can obtain the right materials and expertise.
The world therefore needs to stop treating chemical disarmament as a box that was checked in 2023. It is not finished. The real test of the international system begins when a country becomes too chaotic to police itself. Inspectors need access. Intelligence services need to share information. Chemical industries need stronger safeguards. And when governments collapse, the international community needs contingency plans for securing dangerous sites before somebody else discovers them.
Otherwise, we will continue congratulating ourselves on having eliminated the world's declared chemical arsenals while quietly accumulating an unknown number of undeclared question marks. Yemen should not become another Syria-style lesson learned only after the photographs arrive. The world has spent decades building a fence around chemical weapons. It now needs to check whether anyone has been digging tunnels underneath it.
