I don't know about stagflation, that is also form of inflation, but you simply can't avoid hyperinflation when in just one year you print more than 40% of all US dollars that ever existed.
There is simply too much money in circulation now, and if you read the history you will see that German Weimar Republic did the similar mistake in 1921 and we should all know what happened after that.
They had a huge debt and they believed that winning a WWI would make them avoid paying that, they canceled the gold standard and printed a bunch of worthless paper.
So in reality when countries want to avoid paying big debt, they create war or other type of crisis and that makes me wonder about situation we have now in the world...

https://en.wikipedia.org/wiki/Hyperinflation_in_the_Weimar_RepublicYep, a classic example is the Weimar Republic. While I agree on your general principle of the US not being able to withstand such an "attack" on its value, there is a greatly important difference with other currencies. USD is worldwide accepted in exchange for commodities, particularly gas and crude. The demand for USD is not only derived from its condition of legal tender in US, but backed up by goods all over the world making its demand much more elastic than other currencie's.
