"Restoring deterrence"
Israeli strategic vocabulary, ubiquitous in official briefings across every Gaza campaign.
What it signals
In practice, 'deterrence' is restored by making an example — meaning the civilian toll is not collateral to the message; it is the message. The euphemism converts collective punishment into a security deliverable.
How to answer
Ask what, concretely, communicates the deterrent to the other side — and note that if the answer is 'the scale of destruction,' the doctrine being described is punishing a population, which has a name in law.
