Russia vs Ukraine is much more of a stalemate than Israel vs Palestine (although Russia is still winning.. ish). It is being fought with modern armies on both sides, and the lines of battle have barely changed in months. And it is fought over a huge area.

Thats much different from a conflict over a tiny area, where one side can quite literally bomb every single building in a matter of weeks.

As for how Ukraine vs Russia ends, well probably there will be a continued grinding down of both sides, continued increasing costs, while the borders don't change at all. And then when Russia wants to stop throwing money and lives into a metaphorical pit, there will be some sort of ceasefire/peace deal where Russia gets to keep all the land it took but the fighting stops. Ukraine isn't going to kick out Russia back to its original borders, and Russia isn't going to have some sudden breakthrough where it takes over Kiev. Its sad that Russia will get to keep its gains, but in war there are few good endings and most bad compromises.

But fortunately, Russia simply doesn't have the capability to flatten its enemy on a timeline measured in weeks, and is just stuck in a slog thats going nowhere.

If things had gone differently at the start of the war with Russia's blizkrieg having succeeded well we'd be having a different conversation now about much worse compromises that would have to be made, but fortunately that didn't end up happening.
