Not trying to be a low-effort reply but any Economy 101 textbook will theorize this kind of debt/interest/inflation mix is impossible. Practically, the world is too dependent on the USD in one way or another. If they try to break loose, they might get confronted with those military expenditures which is a good enough incentive to keep using USD as a global reserve currency.
