Before the war there were 44 Million Ukrainians living in the Ukraine
IMO there are about 32 million now.

And a wild guess: 30 million in April 2024

War truce by April 2025 & referred to the UN
for negotiations & peace-keeping.

Subsequent to that, the Ukraine will have to recognise/accept
its new borders before acceptance by NATO as a member.
(NATO wont accept a applicant member with border disputes)

Guerilla warfare for further decades is disputed territories.

Georgia or Moldova will never become NATO members.

All IMO .
