I guess my issue is that it isn't anything new that hasn't been pointed out previously, including Pres. Biden. It is worth noting that the Inflation Reduction Act, particularly the National Electric Vehicle Infrastructure (NEVI) program, specifically has requirements for components and even source materials to be from the US or a free-trade partner (which excludes China). Additionally, there are specific military programs to procure US (or, again, friendly nation)
procurement of rare earth metals.
Personally, this is an area I've been concerned about since the 1980's, when much of our manufacturing was moved overseas. RFK may have mentioned it, but it is an issue that is already being worked on, so it isn't anything new or even unique to him (again, it is something the Biden administration has been working on).
