US Coast Guard Seizes Panama-Flagged Tanker 'Centuries' in Second Venezuela Blockade Action

Major powers have long used naval power to choke rivals’ energy lifelines—from Britain’s 1902 gunboat blockade of Venezuela to the 1941 U.S. oil embargo that helped push Japan toward Pearl Harbor. Washington’s decision to seize a non-sanctioned ship marks a shift from financial sanctions to outright coercive control of sea lanes, echoing the 1980s Iran-Iraq “Tanker War” but this time aimed at a Western Hemisphere producer. It spotlights two structural trends: the U.S. re-militarization of economic sanctions and the growing shadow fleet that enables sanctioned exporters to keep feeding Asian demand. Whether this moment is a footnote or a hinge will depend on follow-through—if the quasi-embargo endures, a loss of roughly 1 % of global supply could tighten oil markets, embolden other great-power work-arounds (notably China’s), and further erode the post-1945 norm of freedom of navigation. In a century-scale view, the episode fits a recurring pattern: resource nationalism colliding with naval hegemony, often a prelude to broader conflict or, occasionally, to negotiated accommodation.
