Follow the money. The financial aspect of the war was interesting in itself, if you can bear finance as an intellectual subject at all. [1] I haven't studied this very deeply but of course the Morgans are involved. Modern wars (starting from around the 18th century) all involve a financial angle and though I feel that certain bankers were criticized for racist reasons, the assistance of bankers in providing and retiring war debt is important. I think it would be likely that my studies would end up supporting the idea that the American side was hoping to fund or supply that which could be conveniently funded or supplied without actually fighting.
