In January 2022, Ireland was facing a terrible dilemma: The Russian Navy had just announced it was going to hold an exercise in Irish waters. Conducting wargames in the exclusive economic zones of other countries is legal, but guests ordinarily ask for permission — and Russia definitely wasn’t a welcome visitor. Like the rest of Europe, Ireland was gripped with fear that Russia was about to invade Ukraine and perhaps other countries. Dublin politely asked the Russian Navy to refrain from holding its exercises, but to no avail. The wargames were going to take place.
But then the Irish government received assistance from an unexpected source. The country’s fishermen declared they wouldn’t allow the exercise to happen: “This is the livelihoods of fishermen and fishing families all around the coastline here,” announced Patrick Murphy, chief executive of the Irish South and West Fish Producers Organisation, on RTE radio. “It’s our waters. Can you imagine if the Russians were applying to go onto the mainland of Ireland to go launching rockets, how far would they get with that?”
The fishermen, Murphy explained, would take turns fishing around the clock. The maneuver made it impossible for the Russians to perform their exercises, and Moscow ended up cancelling the wargames.
The creativity of these gutsy fishermen made global news, but away from the headlines, they and their colleagues in other countries have long been aiding national security. In the early hours of Oct. 28, 1981, two Swedish fishermen on their daily round off the coast of Karlskrona noticed something unusual. They decided to alert the authorities, and the navy dispatched a vessel. What the fishermen had spotted turned out to be the U137 — a Soviet nuclear submarine that had run aground.
The incident demonstrated several things: First, fishermen know their countries’ waters like almost no one else and notice when something is out of the ordinary. Second, the navy — or the coast guard — can’t be everywhere all the time. And third, fishermen can perform a vital service to national security by alerting authorities when something doesn’t look right. The grounded U137 wasn’t a one-off. In fact, fishermen keep a vigilant eye on their surroundings on behalf of their compatriots all the time.
Ireland’s large number of undersea cables is the result of the country’s strategic location at the westernmost end of the north Atlantic and its need for top-notch connectivity to service its high-tech economy. Indeed, the republic has marketed its connectivity — and low corporate taxes — so successfully that a host of U.S. tech firms and other corporate giants have set up European hubs there.
