But I doubt you're going to argue that money was the reason for the Nazis' campaign?
No, of course not. And although not a holocaust denier, I doubt that the reason for invading neighbouring nations was to exterminate their Jewish population (ideology, bordering sadism). It all started over Lebensraum, no? And isn't that, to some extent, an economic issue?
All of which reminds me. When my brother first moved to Germany he advertised for a flat to rent. He wanted the usual stuff: kitchen, bedroom, dining room etc. In his (at the time) rusty German he wrote his ad, but instead of writing 'Wohnen' or 'Wohnzimmer' for living room, he put down 'Lebensraum' instead. The estate agent gently advised him that what he was requesting was an apartment with Austria annexed to it.
