Ukraine will last forever. It's just the Zelensky's government that's falling.
He should have accepted the defeat. Would have prevented lot of destruction that happened in Ukraine. I know that it is there right to prevent their country but sometimes logical thinking is required.
Russia is a superpower, if they just have the intention of ruining all Ukraine structures, they''d already drop thier biggest bombs but I think they don't have that intention. According to the news, the Russians are circling Ukraine to cut the supplies that will force them to surrender. It's an old strategy even in medieval times where the city is circled making the city hungry till they lost the courage to fight. If they have a lot of supplies I guess they can last longer.
When I saw the news about British mercenaries dying and some going back to the borders after just a few hours of going inside Ukraine's borders, I could understand the terror he witness.
