John Maynard Keynes said this quote

The war has ended with every one owing every one else immense sums of money. Germany owes a large sum to the Allies, the Allies owe a large sum to Great Britain, and Great Britain owes a large sum to the United States. The holders of war loan in every country are owed a large sum by the States, and the States in its turn is owed a large sum by these and other taxpayers. The whole position is in the highest degree artificial, misleading, and vexatious. We shall never be able to move again, unless we can free our limbs from these paper shackles.
