At the G7 summit in Evian-les-Bains, France, leaders discussed alternatives to the Strait of Hormuz (the narrow waterway through which roughly a fifth of the world's oil passes) after US President Donald Trump said the strait would be "completely open" by Friday. However, Maisoon H Kafafy, Senior Advisor to the Atlantic Council's Middle East programme, cautioned that history offers little encouragement, noting that during past oil supply disruptions the commercial viability of bypass infrastructure "was simply not there" and upfront investment costs proved too large to justify. The warning suggests that even amid heightened geopolitical pressure, building workable alternative routes to Hormuz may remain economically unfeasible in the near term.
