From what I remember Finland is the only country that has ever repaid their entire war debt owed to the U.S. In the late 1970’s, I remember hearing about a local family of Finnish ancestry, who were quite proud that Finland had repaid the debt and they requested the town fly the Finnish flag with the American flag,for a short period of time, in order to honor/celebrate the repayment of the debt. I thought that was kind of cool.
