"Mowing the grass / the lawn"
Israeli strategic-studies term (Inbar & Shamir, 2014) for periodic military campaigns in Gaza to 'degrade' capabilities.
What it signals
Normalizes recurring bombardment of a trapped population as landscaping — maintenance, not war, with no end state. The metaphor's casualness is the tell.
How to answer
Ask what the grass is in this metaphor, and what kind of policy needs a gardening euphemism. The term is from their own literature; link the paper.
