Yes, we all know that ASML is a multi-national effort, with critical technology components provided by several countries. The point is that the EUV light source is one of the critical technology components and it has not been replicated anywhere else (so far, see xLight founded by Dept. of Energy engineers and funded by the US gov).

It's a bargaining chip that this administration will undoubtedly use to make sure that US access to ASML lithography machines remains undisturbed.
