there is no way the USMC would be able to hold Kharg and the buffer zone without extensive casualties. the buffer zone would be a full-fledged combat zone, non-stop. you'd see Ukraine-at-its-worst levels of drone strikes, and the US military is not equipped to deal with that, not yet.

this is a country that convinced children to charge through minefields during Iran-Iraq; you think pay is going to stop them? or that China and Russia wouldn't give them ample weapons?

there is no winning play here
