Genuine question here: What's the cost-exchange ratio here? Naval mines are cheap, dumb, and can be deployed in enormous quantities. Mine-clearing USVs and drones are comparatively expensive, slow, and bottlenecked on operator attention even when they're autonomous-ish. If one side can lay mines an order of magnitude faster than the other side can clear them, this "drones solve it" narrative falls apart pretty quickly.
Also, stepping back, I'd love to see the strategic objective for this war that aren't Zionist talking points. Every public justification I've seen either assumes a regime-change end state that historically hasn't worked in the region, or quietly relies on the premise that the costs for the war are someone else's problem.
