This NYT article was posted a few days ago talking about how critical China's supply of rare earths are for the US military:
Since the US is on the brink of war with Iran, has there been any analysis or commentary about how the recent rare earth restrictions from China could affect the US military if they go to war with Iran? I would think they would suffer logistical issues but I haven't found any articles talking about this topic (specifically talking about this in an Iran war scenario that is)
