GENEVA (AP) — Switzerland will host scores of world leaders this weekend to try to map out first steps toward peace in Ukraine even though Russia, which launched and is continuing the war, won’t take part. Ukrainian President Volodymyr Zelenskyy’s government didn’t want Russia involved, and the Swiss — aware of Moscow’s reservations about the talks — didn’t invite Russia. The Swiss insist Russia must be involved at some point, and hope it will join the process one day.
