Comparing a currency issuer like the US to currency users like Italy and Greece is a category error. You can compare Alaska to Greece or California to Italy. But you should compare the US to other currency issuers - like the Eurozone, Japan or the UK.

Euro area is slightly under 90%, doing a bit worse than EU average (80%ish).

Japan is much higher-- I did not have that in my dataset, appears to be at 230% debt but decreasing pretty rapidly (down from almost 260% in 2020).
