I don't think the US will allow that. They probably have enough leverage.

I think they squandered that recently. We will see with Biden but the Trump administration basically encouraged Brexit and repeatedly adopted anti- EU positions in key geopolitical issues (Syria, NATO, Iran, Israel, and Ukraine). These things come with a cost and the EU will try to rectify this. Enhancing Chinas CPU tech by a few generations might be worth it if it can advance EU interests and ensure future good-faith from a supposed ally.

It's not their decision. The ASML scanners rely on many critical US-origin technologies and the US can block shipment unilaterally.

Enhancing China’s CPU tech even a single generation is in the EU’s interest in exactly 0 alternate universes, along with this one.

As long as the US has the world’s only reserve currency and as long as the EU economy - especially the productive bit in the North - is built on exporting to the all-powerful US consumer, the EU has very little leverage in its affairs with the US.

> the EU has very little leverage in its affairs with the US.

The final word has not been spoken. Construction of Nord Stream 2 has recently been restarted despite the US threatening with sanctions.

This thinking is how you end an empire

And in every case the US was right and the EU was wrong.

Only a fool would tie themselves to China as things stand right now.
