Isolationism could be part of the American political culture due to its origins of that state

Like with China and its political goes back to the Shang dynasty and why China has a very different view to monarchy then Japan and England

For the Japanese and the English they have no issue with a powerless head of state and hereditary ruler

I do wonder if China would have been better of if Cao Pi did not end the Eastern Han empire

Their benefits having a head of state who is unelected and powerless but gets the love and prestige of

The American president

I do wonder if it's bad that the USA president gets the love and affection of a king / Queen which we can see with Trump can be bad for the nation

But it's tool late the American political architecture and culture has already been constructed and it's almost impossible to reconstruct

If you are an American today you are living in a house that is already built and you can not design your own home

I hope my analogy make sense
