Surrender for Ukraine is no more an option than it was for Israel in June 1967 when Nasser said the only Jews left alive after the war would be good swimmers. Surrender = genocide, as Putin's mouthpiece Timofey Sergeytsev, made clear in Ria Novosti: https://www.memri.org/reports/russian-columnist-sergeytsev-ukranian-nazism-greater-threat-world-german-nazism .

The same would be true for Estonia, Latvia and Lithuania based on previous experience. https://latvians.com/en/Exile/Siberia/Latvia_deportation_1941.jpg

Come to Latvia and I'll show you this deportation railcar used in 1941 and 1949. It's still there.

The Germans, Swedes and Russians occupied the Baltics for more than 700 years. Now they're free.

Ukraine has been in a cultural and/or military war for its independence since the mid 19th century. The inevitable outcome: same as the Baltics. Russiaw ejected and Ukraine sovereign and free.
