You've got the causality backwards. Pulling back from the world and ending the US as a source of stability will destroy the status of global reserve currency. And the focus on the "deficit" (which tacitly ignores all the artificially-cheap loans given to the financial industry by the Federal Reserve) is just a kayfabe partisan point rather than a real analysis. In actuality that high price inflation from the first Trump term caused the first shred of fiscal responsibility from the Fed that we've seen in over two decades. Our country would be in a much better state if monetary creation could have continued with deliberate spending on domestic industry rather than being directed back at the everything bubble plus some magical-thinking tariffs.
