Deploying on Kharg Island would surely be extremely risky if missiles could still be launched from the mainland. From what I can see announced, no massed build up of ground forces appears ‘imminent’. A relatively small number of marines, yes, but it would take months to assemble the numbers required to establish a secure foothold along the southern coast. In the meantime, the chokehold would remain in place and prices would only continue upwards.
This whole fiasco has exposed fundamental problems in US thinking. Politically, diplomatically, economically, militarily, and strategically, the folly of sidelining experts and allowing transactional businessmen free rein is all too apparent.
