We know what Russian President Vladimir Putin wants in Ukraine: to wipe the country off the map.

We also know what Ukrainian President Volodymyr Zelenskyy wants: to keep Ukraine alive as a democratic state. The question is what the West wants. What is its strategic goal?

So far, the West’s objectives have been framed in the negative: to avoid being drawn into a war with Russia, while still doing whatever possible to help the Ukrainians. That has meant saying no to Zelenskyy when he asks for a NATO-enforced “no fly zone.” But the West’s war strategy cannot be built on what it will not do. NATO and its allies must define a positive objective.
