The most likely outcome of Kyiv's spring counteroffensive will be a stalemate, says retired US Army Lieutenant Colonel Daniel Davis. However, given the much more significant reserves of human and physical resources at Russia's disposal, over time it is likely to simply crush Ukraine.

The most realistic choice that Zelensky now faces is either to start negotiations on a cessation of hostilities so that Ukraine can retain what it has now, or to continue to fight and ultimately lose even more territory, says Davis.
