Operation Pillar of Defense begins

The beginning of Operation Pillar of Defense marks a major escalation in the long cycle of Israel-Gaza confrontation after years of blockade, rocket fire, targeted killings, and periodic military operations. This start marker matters not because it was an isolated strike package, but because it captured the moment when coercive signaling turned into a short, intense war with regional and international consequences. It matters because some operations are historically important less for territorial change than for what they reveal about deterrence, escalation control, and the limits of force in recurrent asymmetric conflict. The start marker is connected to the killing of Ahmed Jabari, to the broader Israeli-Hamas confrontation in Gaza, and to the way the operation fit into a repeating pattern of military pressure followed by mediated ceasefire. It matters because the opening of a limited operation can reveal how both sides try to shape political outcomes without fully resolving the conflict that keeps producing new rounds of violence.
