Tesla manufactures/assembles about as much as any other western car company.
Honda is the only one who comes close to Tesla.
And is the relevant measure, as all auto manufacturers employ job shops for various parts.
I don't care if Tesla or Honda manufactured a part in a building under their logo. I care that they invested in US infrastructure and paid US citizens to build the car I drive. That's what country of origin measures.
Heaven forbid we have to fight another war and all the factories and skilled tradespeople are in Mexico or Canada.
We can keep going back and forth. It doesn't change the numbers.
