To give an anecdote to your first question: I've sat on earnings calls for big , high-tech manufacturers where the gist basically was expressing dismay that "we've been cut out of these markets due to sanctions / trade wars. This is a hit to potential earnings. We're a global company blah blah blah."

The personal ideological convictions of the capitalist doesnt really matter because as a whole capital knows no loyalty to anything but it's growth and ever-increasing exploitation. it can't be controlled.

And its also cathartic because death to America ;)
