Russia’s indiscriminate attacks against Ukrainian civilians—including bombing hospitals and schools as well as the use of horrific weapons, such as cluster bombs and white phosphorus—should drive the West to reevaluate its war engagement policy and take a more active role by implementing a no-fly zone or securing evacuation corridors—perhaps even actively fighting Russian forces.

The main concern is any such escalation could lead to World War III. There are reasons that this is unlikely.
