In no realm does the US consider Japan, Germany, or Singapore a rival. China is the only “rival” in there. The other countries don’t have the actual quantity of people or land size to be an economic rival. At best they could have a higher standard of living based on PPP or GDP per capita, but not anything that would overtake the US. You’re trying to turn a simple evaluation tool that every government should be using on its trading partners into some maniacal weapon of economic doom. There are lots of partners in this world. Just like everyone else if you act like everyone is an enemy then all you ever see is targets.
These days I’m usually against the death penalty, and I know it seems a bit harsh to advocate for this… but people entering in an exit door should be absolutely blasted with an Anti Aircraft gun (thanks Kim Jong Un for the idea!). It absolutely rustles my jimmies.
