  The armed invasion of Ukraine by the Russian Federation has adversely
affected the relations between Russia and Western countries. Among other
aspects, it has put scientific cooperation and collaboration into question and
changed the scientific landscape significantly. Cooperation between some
Western institutions and their Russian and Belarusian partners were put on hold
after February 24, 2022. The CERN Council decided at its meeting in December
2023 to terminate cooperation agreements with Russia and Belarus that date back
a decade. CERN is an international institution with UN observer status, and has
so far played a role in international cooperation which was independent of
national political strategies. We argue that the Science4Peace idea still has a
great value and scientific collaboration between scientists must continue,
since fundamental science is by its nature an international discipline. A ban
of scientists participating in international cooperation and collaboration is
against the traditions, requirements and understanding of science. We call for
measures to reactivate the peaceful cooperation of individual scientists on
fundamental research in order to stimulate international cooperation for a more
peaceful world in the future. Specifically, we plead for finding ways to
continue this cooperation through international organizations, such as CERN and
JINR.
