**Deck**: A maritime security expert argues that control of sea lanes is turning into a central arena of geopolitical rivalry as U.S. naval dominance erodes, China expands at sea, Iran holds a key position near the Strait of Hormuz, and Russia develops the Northern Sea Route.

A maritime security expert warns that global trade routes are emerging as a key arena of geopolitical competition, as long‑standing U.S. dominance at sea faces pressure from several rivals.

Control of sea lanes has long shaped trade, navigation and military mobility. The expert argues that Washington’s traditional advantage is gradually narrowing as China builds up its navy, Iran maintains leverage around the Strait of Hormuz, and Russia pushes development of the Northern Sea Route along its Arctic coast.

China’s naval expansion gives Beijing more options to project power and influence shipping in nearby waters. Iran’s position around the Strait of Hormuz, a chokepoint for seaborne oil exports, lets it exert pressure on tankers and energy flows. Russia’s work on the Northern Sea Route seeks to turn an increasingly ice‑free Arctic passage into a strategic and commercial asset.

For global trade, these shifts mean that the cost, timing and security of shipping can be affected by political decisions along a few critical corridors. For navies, they complicate planning and raise the risk that regional tensions will spill over into disruptions of maritime traffic.

Signals to watch include growth in China’s ocean‑going fleet, Iranian activity around Hormuz that affects commercial vessels, and Russian moves to formalize rules or fees along the Northern Sea Route as climate change opens more of the Arctic to navigation.
