Claim: Bertil Ohlin debated with John Maynard Keynes who predicted a war caused by the burden of debt.
Evidence: In 1929 he debated with John Maynard Keynes, contradicting the latter's view on the consequences of the heavy war reparations payments imposed on Germany. (Keynes predicted a war caused by the burden of debt, Ohlin thought that Germany could afford the reparations.)
