the United States sold various resources (including tungsten for armor-piercing shells) to the fascists
Are you sure about this? My understanding is that the allies sought to limit availability of tungsten to Germany, given that Spain happened to have large deposits of the stuff.
Well, I'm quite willing to entertain this claim, but your response doesn't provide any details about who sold tungsten to Germany during this period. I don't want to go on a wild goose chase learning about the US tungsten industry of 80 years ago, nor learn Russian. If you could cite some specific companies that'd be great. As I pointed out, most of Germany's tungsten came from Spain, which has tungsten deposits in abundance.
Should you have enough time in the future, I could share with you also my monograph (currently in draft) on the long history of the current conflict Russia is involved in. Thousands of archival documents, links to sources etc. And the document is being composed in English, so I hope there won't be any problems reading it.
