European particle physicists have updated their strategy for the coming decades. Beyond current commitments, the community advocates pursuing a new facility at the CERN site outside Geneva—a circular collider with a circumference of 100 kilometers. Such a machine could serve a dual purpose: to act initially as a “Higgs factory” where electrons and positrons smash together at energies up to 350 GeV, and to later scope out the high-energy frontier by colliding protons at up to 100-TeV energies. The feasibility of this so-called Future Circular Collider (FCC) is still an open question, which is why the strategy also calls for continued research and development into accelerator technology, such as plasma acceleration and muon colliders.

I was wondering what was going on, if anything.

I doubt they could get the money to even build that in the near future and it reminds of the one they tried to build in Texas almost 30 years ago and after they started that one they decided that $4billion was too much to spend (politicians of course)

Yes, I know that story more or less. I think they are better off in France/Switzerland.
Money could be a problem. No one knows if any government will have any.
