You're not wrong about tribalism, but as a fellow American, Europe can either trade with a brutal dictatorship for EV chargers, trade with a brutal dictatorship engaged in war on their doorsteps for natural gas, or keep on depending on a insipient wannabe brutal dictatorship's military to keep oil trade via sea going. I think the EU is techie enough that if China turned off the chargers somehow for some reason they could nationalize and lobotomize the hardware, but compared to America and Russia they aren't really as likely to come to blows.
