The FED needs to be cautious now that USA cannot prop up its exceptional privilege with military force. Without China supplying rare earths the US military monetary combine is significantly disabled. USA cannot now fight a war of any significance and duration without China resuming supply of rare earths. Monetary and military power structures are very closely aligned. The neoliberalised west forgot the strategic importance of actual ability to make and refine strategic materials and products. Now it is at the mercy of Chinas mercantile mixed economy. Best to keep what little monetary and military powder it has left, dry.
