It did not go into a hyperinflation after the WW2, when the US debt load as a share of GDP was even higher than today; and deflated in the same way US is likely to do it now (bond rates forced way below inflation with yield control).
I am not saying that the process will be pleasant for the US or its citizens. But it is not without precedent and is extremely unlikely to cause hyperinflation. My 2c.
The post WWII economic boom outgrew the debt thus dramatically decreased the debt to GDP ratio.
The US is unlikely to find itself the only industrialized nation without massively damaged infrastructure again anytime soon.
