The size of the US national debt does not matter. The US will always* be able to pay its debt as long as its the central economical/political/military force on this planet. It can always make more dollars if it deems that necessary and always has done so in the past. And as long as you build functional and necessary state things, every economist and every journalist that points at the debt needs to be bullied and stuffed in a locker. Debt matters to nations depending on IMF/US loans and that’s an entirely different issue.

However if all your burger nation pays for is bombs, genocide, brown shirts, fat cops with tanks, wall street losses, ai bubbles, real estate bubbles, jeffrey epstein flights and failsons crack adventures abroad… You might not get a good “return of investment” as they say and you devalue your own currency for very little long term benefits.

But these things in itself are already dissolving the societal connections much more than an additional 0.5% inflation due to debt. The real “inflation” is the direct result of ever increasing rent seeking, quasi monopolies, disfunctional social systems and the short term demands of share holders. I.e. captialisms core mechanisms. And the real damage is not to your financial health, but is literally just large scale physical and mental violence to an ever increasing amount of people.
