In the special on America, Indy explained that the U.S. only lent $27 million to the Central Powers during the war. Still, $27 million is a fair bit of cash, so who in America was lending it? Was it illegal or difficult for Americans to lend to the Central Powers? What were the logistics of getting cash to, say, Austro-Hungary? My understanding was that bonds and securities were pieces of paper that physically had to be transported. For example, the German cargo submarine Deutschland partially carried physical paper securities during one of her supply runs to America.
