The United States is a bully in a China shop and that China shop is the world. It constantly destabilizes the Middle East under false pretenses and lets Europe pick up the refugees. It brain drains and takes innovation to be commercialized. It makes money on the hard labor of others.
So yes probably for the best for Europe to do what China is doing and decouple.
Specific examples: Francis Lowell stealing British Loom designs in 1800.
Bessemer steel process replicas.
Bell vs European Telephone patents.
Radio: Marconi was initially backed in the US then Bell filed the patents.
Operation Paperclip and all that entails (thousands of German patents invalidated and filed in the US).
