I don’t think people would have a problem with driving a fast car either, you enjoy what you enjoy. Just respect the limit and the lives of others around you. Or go crazy on a circuit.

The US only joined the allies because of Japan’s war declaration. They were mostly happy making bank with both sides before that.

The communications systems in german tanks were working with Graham Bell technology. Their electronics were big on american parts too. Part of the oil that fueled the invasion of Poland and France was from the US. A big part of US’ elites were pro-Hitler (for them the guy was a godsend against communism). The safest places to hide during the American bombings in Germany were the IBM factories.
