Not exactly breaking news, but it still shows the scantiness in the minds of our current leadership. To give up even on the possibility that some form of production can be present in places with such a tradition of assembling cars just shows that their hubris heavily overrides their judgment. Also, this just shows the workers and the general public that at this point they can do anything. If they did this, who is going to stop them from dislocating all of the production out of the US.
