That comes out to foreign debt consisting of something like 2-3% of GDP. In the US, in the present day, foreign debt is like 6% of GDP.
By contrast, for what it's worth, France's payment to Germany after the Franco-Prussian War was about 22% of GDP. Paid over 3 years, so the payments themselves would have constituted like 7% of GDP.
Germany imposed another massive financial penalty on France after defeat in June 1940, too. I don't have the exact figures on me, but it was a) stupendously large and b) accumulated daily and paid monthly.
