The undersea cable network, the unseen backbone of global communications, carries 95 percent of international data, including financial transactions, military communications and internet connectivity. Despite its vital role, this infrastructure is both vulnerable and poorly defended, lying exposed on the ocean floor and shielded primarily by its obscurity.

Recent incidents in the Baltic Sea and near Taiwan have underscored the risks, with evidence suggesting that powers such as Russia and China are testing the West’s resolve to protect these critical lifelines.

Last month, two undersea cables in the Baltic were severed, disrupting communication between Finland and Germany as well as between Sweden and Lithuania. Suspicion has fallen on the Chinese-flagged bulk carrier boat Yi Peng 3, which was reportedly dragging its anchor across the seabed near the cables while transporting Russian cargo. Investigators believe this may have been an act of sabotage involving tacit cooperation between Beijing and Moscow.

Meanwhile, in Asia, undersea cable disruptions near Taiwan have raised concerns that China could be probing vulnerabilities in anticipation of a potential crisis.

These developments should not lead the West to panic or overreact. While the growing threat to undersea cables is real, it is neither insurmountable nor requires a dramatic escalation of tension. Instead, a measured response is needed that strengthens resilience without adding fuel to an already volatile geopolitical environment.

The risks stem from two primary........
