NATO's Rot to Ukraine:
It doesn't seem very likely that anyone will win this war outright.
We must hope that this war will be brought to an end, although it is unlikely that Ukraine will regain all of its territory.
What Ukraine is willing to accept in a deal depends entirely on Ukraine.
Only Zelensky and his government can decide this on behalf of the Ukrainian people.
But these kinds of wars always end in a peace agreement, and this often involves compromise.
