Where would they move to? I don't see them moving anywhere. The page says maybe France, but I think that's unlikely.. higher taxes there I believe and a different language.
A lot of dutch people already spend all their summer vacations here (along most of the beautiful and peaceful rivers and places of the French countryside) they know the place, the language will follow. And most educated French people talk some form of English.
The US where their core IP and largest bleeding edge R&D center already is.
And becomes a hostage of the politics.
It already is, their EUV IP is licensed from EUV LLC which was formed by the DOE and the researcher labs under congressional oversight.
The light source for their lithography machines is made in the US.
The USA probably the US government already owns their core technology.
