While in an ideological sense terrorism is an act of evil partially differentiable from “normal war”, viewed strictly through an abstracted lens in terms of military tactics it is clear that terrorism is also a form of guerilla/asymmetric warfare that warps spectacle into fear and attempts to create power from a weak position.

It is NOT a tactic undertaken by a military that is curb stomping another military’s air defenses, ground forces and logistics, there is no need to exploit the leverage of terror when you have the ability to directly dismantle an enemy military’s war machine while taking and holding territory.

Terrorism is what desperate people with no moral red line resort to when they are unable to materially fight a fullscale war against a perceived enemy, which is why russia leans on terrorism as a tactic.

This is traditional war on Ukraine’s part and this accusation is just projection.
