Gnu:
Nice link, but possibly not quite factually accurate. I quote:
Japan and, to a lesser extent, Britain and Italy, were lifted out of the debris of war by the Americans who poured in billions of dollars and forgave other billions in debts. None of those countries is today paying even the interest on its remaining debts to the United States.

That paragraph is somewhat rebutted by the BBC website BBC, which says:
The UK will repay debts owed to the US dating from the World War II by the end of this year, the government says.
Under the lend-lease programme, which began in March 1941, the then neutral US could provide countries fighting Hitler with war material.
The US joined the war soon after - in the wake of the attack on Pearl Harbour - and the programme ended in 1945.
The final payment of £45m will be made by the 31 December, meeting a 1945 obligation to repay the debt in full.
