Even on the 1930s, US Oilmen, from the Majors down to small Wildcatters, swarmed around the Globe, even the USSR till the Purges got rolling, for the search for Oil. But not in the Italian Sphere, as far as I have been able to ascertain. Wasn't the only US sector, either. Italy was about the only country to make business difficult enough to close down operations for FoMoCo. Yeah, Henry Ford, who could make deals with both the Nazis and Communists, and even Japan, gave up under the restrictions that FIAT was able to lobby for. Same for most other US manufacturers. That push Italy had for self sufficiency and Autarky did not help, and I don't really see a way around that.
