I'm confused. You have to pay me 100 bucks, but no worries, I'll loan you 80 bucks over 20 years to help your finances.
You'll have to give me 240 bucks.
I'm not that familiar with the details, but it would be more like:
- You owe me $1B in reparations, with $10M payable each year for 100 years
- You can only come up with $8M this year, so I loan you $2M
- You then borrow from someone else to pay me back
Kind of like a rolling credit that is more about cashflow than debt level. Countries like the US were worried that Germany would just run out of cash at some point.
