Lasting for six years, the Second World War was the most expensive war in history.

In today’s terms, the war cost over $4 trillion, but who paid for it? This documentary examines what happened after Britain ran out of cash to pay for the arms to fight with, how this had global consequences and how the strength of American arms turned the tide on this most bankrupting of conflicts.

Featuring impressive archive and interviews from leading academics Richard Overy, Yasmin Khan and Mark Harrison.
