I'd be curious to understand the interest rate the US government is paying on the debt verses some other highly indebted countries.

I poked around on google, and it looks like China has around 50% Debt to GDP ratio , Japan had something like 250%, and Russia's was around 20%. I have no idea what I should conclude from this -- other than I don't think it's possible for someone to foreclose on the US for not paying it's debt --- and that if we had massive inflation, and Debt is not inflation adjusted you could drastically reduce the debt -- but you'd have to increase the interest rate on new debt you were issuing.
