we have been servicing the debt for a long time, many years, and the world is still spinning.. if you are old enough, you remember when Carter was President, and we had about $30 Billion in deficit.. the nay sayers were saying our economic system would collapse under that debt.. our Economic textbooks and pundits declared that increasing debt would spiral inflation.. cause bond interest rates to escalate.
well inflation did spiral, and bond yields jumped.. for a short time.. enter Reagan and a new vision of debt management, not only in the US, but worldwide.. it is not only our Country that has massive deficits.. and this debt has reached crazy proportions, absolutely unheard of or imagined 20-30 years ago.. and?
we currently have the lowest 10 year bond yields in history.. negative interest rates in a few, and growing, Countries. inflation is tame, and has been since the 1980's.
what do you have to say about that?

4. How much of the debt is owed to foreigners. This is particularly important if the debt is denominated in foreign currencies, which is a problem we don't have in the USA.
5. O.K., the final item I don't really understand, but the fact that the U.S. is the world's largest reserve currency could enable us to bear a higher level of debt as a % of GDP than other countries. I've read that, but am not sure if it's really true.
You saw a meltdown in Greece when government debt as % of GDP approached 170% of GDP. Interest rates went to double digits, mostly because investors and savers doubted the ability of Greece to pay back the debt.
There were meltdowns in Asia in the late 1990's at much lower levels of government debt as % of GDP in places like South Korea, Thailand and Indonesia, maybe 50% or 60% of GDP. In these countries the big problem was too much debt owed to foreigners, a weak currency, and high interest rates. Something similar happened to Argentina around 2001. Because a lot of the debt was denominated in dollars, they had a double whammy. Foreigners were taking their money out of these countries, which caused their exchange rates to get weaker, which made it harder to pay back the dollar debt. It was a vicious circle.
Japan has been able to sustain a very high level of government debt to GDP, in excess of 200%, because interest rates there are very low (in fact negative right now, all the way out past 10 years maturity) and because it doesn't have much debt owed to foreigners. However, economic "growth" has been horrific, often negative.
I believe the current level of government debt to GDP in the USA is around 80%. The problem, in the long term it will inevitably go up a lot, to levels in excess of 250% of GDP, if we don't get entitlements under control. See this from the General Accounting Office:

At the much lower levels we have now there's still potential for a crisis. You pointed out what happened under Carter. At that time, government debt as % of GDP was much lower than it is today, around 30%. However interest rates were much higher, and the burden on the government in terms of interest payments was high compared to the level of debt. If inflation kicks up or if for some reason the government has difficulty borrowing and has to pay high levels of interest, then we could get into trouble, like we did under Carter.
The USA historically has bought a lot more from the rest of the world than we sold to them. As a result, foreigners have accumulated a massive share of our government debt, so I wonder if the same thing could happen to us as did to South Korea, Thailand, Argentina, etc. I'm not sure what the probability of that is though, as maybe having a reserve currency would reduce the probability we'd have a crisis. And we don't have the problem they did with debt denominated in foreign currencies.
Anyway, at some point we will have to pay the piper if we keep on the current course. I don't think government debt as % of GDP over 150% is sustainable, and that's where we're headed.
