Okay without trying to start a flame war here (this is a genuine question not an argument) it is my understanding that every nation on Earth has a national debt and that those "debts" are pretty much used as a sort of credit system for a nation, for example say UK owes US 5 billion dollars but instead of being forced to pay it streight up they'd be asked to back the US in a UN vote or something of that nature instead.
Now I was only using US UK as an example but is that true that often nations pay their debts to one another through non monetary means?
I mean face it if the United State called in every debt we were owed we'd get a few trillion bucks to pay off our own debts but we'd also bankrupt many nations in the process and likely be bankrupted afterwards ourselves?
Like I said I'm not doing any political US is superior stuff here I am just trying to figure out why I've heard so many people saying "national debt is a political plus sometimes". I mean I am far from a professional economist so heh
