From the Strait of Hormuz to the North Sea, maritime conflict is spreading across the globe, and the cost goes far beyond oil prices. The collapse of international cooperation on the high seas signals something far more ominous: the unraveling of the rules-based world order that has governed ocean commerce for centuries.
The pattern is unmistakable. The Trump administration's military assertion of control in the Strait of Hormuz to protect American shipping echoes a strategy nearly 200 years old, when a US naval squadron defended merchant vessels from corsairs in the Mediterranean. Then as now, the mission boils down to one thing: protecting trade and business interests, stripped of any larger ideological purpose.
What has shifted is the fundamental legal framework. For generations, the principle of freedom of navigation, rooted in 17th-century Dutch jurisprudence, anchored maritime law. No nation had the right to charge tolls or demand fees for passage through international waters. That consensus is cracking.
Secretary of State Marco Rubio declared in June that no country could impose such charges. Yet the administration soon suggested the US itself might do exactly that. A recent memorandum with Iran now acknowledges its right to monetize transit through the Strait of Hormuz. The hypocrisy is striking, but it reflects something larger: Trump's view that nation states, particularly the US, operate without constraint from treaties or regard for shared global resources.
The precedent is spreading dangerously. Houthi militias in Yemen have begun blockading the Bab al-Mandab strait at the mouth of the Red Sea in retaliation for Saudi attacks, disrupting oil shipments and destabilizing markets. Indonesia is now debating tolls in the Strait of Malacca, through which 22 percent of global maritime shipping passes. Similar arguments could follow in Turkey, controlling the Bosphorus, or Spain, dominating the Strait of Gibraltar. Since 80 percent of goods traded worldwide by volume travel by sea, the implications for global supply chains are severe.
Beyond commerce, military confrontation is intensifying across multiple fronts. China's militarized artificial islands in the South China Sea and its clashes with the Philippines show Beijing's willingness to reject international law when inconvenient. Last week, a Chinese missile destroyer conducted a live-fire drill inside Japan's exclusive economic zone near Okinotori. The timing matters: this came after Japan's new prime minister suggested Tokyo might intervene militarily if China moved against Taiwan.
Russia presents an equally destabilizing force. Its Black Sea fleet, battered by Ukrainian missiles and drones, now focuses on sabotage. Russian warships have expanded operations in the Atlantic, North Sea, and English Channel, suspected of mapping underwater infrastructure for future attack. Last Monday, a Russian warship conducted a live-fire drill 45 miles south of Plymouth on the day Britain's new prime minister took office. That same month, a Russian frigate fired warning shots near a private yacht off the Isle of Wight.
These incidents, seemingly isolated, form a pattern of deliberate provocation designed to test defenses and signal contempt for established maritime rules. A Russian frigate accompanied the Chinese warship that drilled near Japan, underscoring a broader realignment.
The lawlessness extends beyond great powers. The US sank an Iranian warship off Sri Lanka in March. Trump has renewed threats to seize Greenland and bomb civilian boats off Venezuela. Australia faces outrage over China's submarine ballistic missile test in the South Pacific, even as it acquires its own nuclear-powered submarines.
This cascading disorder is driving a global arms race. Britain, facing mounting pressure to strengthen its military, must now expand spending significantly, particularly on a badly depleted Royal Navy. Nuclear deterrent upgrades are planned. The cost in money and geopolitical risk is climbing.
What unites these crises is the collapse of maritime cooperation protocols refined over centuries. Questions of free trade, offshore defense, sovereignty, borders, fisheries, deep-sea mining, and environmental protection once operated under agreed legal frameworks. Now the stronger simply impose their will, dismissing concepts of global commons or shared space. It is gunboat diplomacy for a new era, and the world is adrift.
Author James Rodriguez: "When every major power treats international maritime law as optional, the system doesn't just weaken - it dies, and chaos takes its place."
