Earlier quoted context omitted.
Because RISC V results would be something the Europeans could produce? We are reliant on the US as only 2 companies can make the x86/64 chips. I don't think Europe would be completely against working with a US or Chinese company like Hi Five/Star Five, as long as we weren't dependent on them, and could pull ties if they abused their position of control.
STmicro is producing chips at around 14-18nm. ASML is the one producing the leading lithography machine, and we are not talking about ARM, Infineon or NXP. Europe has the capacity to produce their own processors if needed.
On this, Trump's policy of putting tariffs on chips manufactured in Taiwan makes sense to make it worthwhile to put the fabs in Europe.
