I am aware of the delusion very well, what I am talking about is the consequence of people living on that delusion. It is like how to handle a flood water. If you divert the water by various gentle ways you will have less damaging small floods, if you build a dam trying to block the water to go anywhere you will get a sudden burst and catastrophical disaster. What you suggested that US might do is the later which will be more harmful to themselves. Trump's trade war is actually the perfect demonstration of that path.I think you don't realize the delusion in US and the west in general and also the US worshippers in east Asia and gulf arabs. They think US is invincible. It has the most innovation and the best system of government in the world.
That's why US tech companies have market values in the trillions while their Chinese alternatives who are actually selling products several times cheaper and gaining market share are valued in a few billion.
Faith in US will not go down easily among it's worshippers
I am absolutely not going to convince US not to do that though.
