I don't disagree with you, that's why it's important for many countries to decouple to minimise the potential aftershock. The question is if politicians in respective countries have the will to do so.

Europe is slowly decoupling from US tech, fortunately.

Another kitchen will take its place; always have. Now, whether you agree or not, the next kitchen is likely to be China.

And not to completely dismiss your point, but like I said in another comment, it's important to decouple from the kitchen that is US to minimise the consequences. I don't want another repeat of the Roaring 20's and the countries too economically intertwined with the US also collapsed when the Great Depression hit. One of those countries who was dragged down the worst was Germany, when American investors pulled out their investments from the country. That severe aftershock gave rise to the Nazis, and the rest is history.
