Supply chain diversification is certainly not a problem; it can even be considered excellent. However, supply chain diversification isn't the opposite of independence; it should be a complement to it. You need independent capabilities to survive external changes. Supply chain diversification, on the other hand, allows you to thrive even when external conditions are favorable.
The problem in Europe is that they've placed too much faith in supply chain diversification and almost completely abandoned independent capabilities.
