The two are not mutually exclusive, and the set of people who could work on either of these is probably mostly disjoint. "Don't fix problem X because problem Y is more important" isn't a helpful stance if we can work on both.
My comment was meant to point out how frequently the Geneva Convention is ignored by nations today. Clearly we need a similar convention to protect our increasingly critical digital infrastructure. However, our inability to enforce the current convention does not bode well for enforcing this one. It's tough to see how we can compel nations to comply until international law as a whole is better respected by all nations.
