"The decision to end the cooperation agreement was taken in December 2023 when CERN's Council passed a resolution "to terminate the International Cooperation Agreement between CERN and the Russian Federation, together with all related protocols and addenda, with effect from 30 November 2024; To terminate ... all other agreements and experiment memoranda of understanding allowing the participation of the Russian Federation and its national institutes in the CERN scientific programme, with effect from 30 November 2024; AFFIRMS That these measures concern the relationship between CERN and Russian and Belarusian institutes and do not affect the relationship with scientists of Russian nationality affiliated with other institutes." The cooperation agreement with Belarus will come to an end on 27 June, before the Russian one ends."
Cern is uninvolved, they just don't want the conflict to be an issue on property. Ukraine was invaded, Russia invaded so they booted Russia and not Ukraine.
It would make total sense if reality matched your description. A regular russian-by-nationality physicist could never just go and apply to a CERN job, thew website immediately rejected then on the basis of nationality (tested in 2018) because Russia never pitched in and paid a fair share proportionate to its GDP. In reality, CERN always sneaky-hired Russians in obscure ways that dissociated them from their governments (at the very same time, my colleague worked and lived there on-site for what, 7 years as least?).
Thus whatever scheme CERN has terminated was already the scheme that hired people and avoided dealing with the government. One of those so desperately needed to drain Russia of talent. Explain me how on Earth is that helping anyone but Russia.
These aren't 2.0gpa party school kids. These are generally PhD or PhD students who would have exactly zero difficulty leaving to the US because the US will simply give them what they want to brain drain Russia. We spent literally hundreds of millions of dollars doing this from 1946-now. The theory being farmers don't build great missiles and scientists and engineers are in shorter supply.
It's impossible to recall the context because somebody keeps removing my comments, but I get the gist: you're telling an actual former PhD student from Russia who has long moved abroad how the rest of the world aCtUaLlY treats Russian scientists and PhD students.
