Author’s note:
This essay is Part IV of The Iran System, a series on the Iran war and the systems it is forcing into alignment toward a new world order. The previous essays mapped the Shia axis as the old order’s embedded machine and the Sunni field as the old order’s managed fragmentation. This essay turns to the third system: Israel, not as the driver of the broader reset, but as a state whose own doctrine has been hardening in advance of it, and which is now being tested by the very realignment the United States is trying to force through the Iran war.
1. The shift began before the Iran war
The easiest mistake is to treat Israel’s current posture as a sudden product of the February 28, 2026 war with Iran. It is not. The Iran war has intensified and widened the posture, but the doctrinal turn predates it. What changed inside Israel over the last decade was more fundamental: the old logic of deterrence and periodic containment was giving way to a more ambitious ambition—to shape the strategic environment itself, not merely survive inside it.
The devastation in Gaza was the most complete expression, before the Iran war, of a doctrine that had already moved beyond “absorb, strike back, restore deterrence.” The target was no longer only the militant organization. It was the environment that allowed the organization to govern, hide, move, replenish, and return. The destruction looked new in scale.
2. The inherited playbook: manage, degrade, repeat
From the 2008–09 Gaza war through the 2012 and 2014 campaigns and the 2021 escalation, Israel repeatedly returned to a doctrine that analysts themselves came to call “mowing the grass”: recurrent, high-intensity operations designed not to solve the Gaza problem, but to reduce capabilities, restore deterrence, and buy time. The phrase was not invented by critics after the fact; it was already present in Israeli strategic literature well before the current war, and by 2021 it was common enough that major coverage treated it as the shorthand for Israel’s operating concept in Gaza.

This was realism of a particular sort. Hamas could not be politically integrated on acceptable terms. Gaza could not be pacified at acceptable cost. So the system would be managed, not settled. Force would be used episodically but decisively enough to re-establish temporary order. The premise behind that doctrine was not that the underlying reality would disappear. It was that it could be cut back repeatedly and kept within tolerable bounds. That premise also shaped Israel’s approach to Hezbollah after 2006 and to Iran through years of covert escalation, sabotage, and shadow war. It was still the old-order logic: compartmentalize the problem, impose costs, defer resolution.
3. The Shift in Doctrine
October 7, 2023, shattered confidence in that model because it showed that the system Israel thought it was managing had evolved far beyond the thresholds its doctrine assumed. Hamas’s assault killed about 1,200 people, took more than 240 hostages, and punctured one of the most technologically surveilled borders in the world. For Israelis, the breach was not merely tactical. It made clear that deterrence had not failed at the margins; it had failed against a system that had become more embedded, more deceptive, and more patient than the framework of management had admitted.
What followed in Gaza was therefore not simply revenge or loss of temper. It was the beginning of a harder doctrine.
