Oh, I see now. I mean, I don’t disagree that the most aggressive way for the ICRC to handle it would be to claim it as some kind of emerging customary norm rather than trying to whet appetites for a new AP to address it. You can never be sure what the results of treaty negotiations will be. Failure to ratify an AP would be positive evidence that there is no such norm. So why risk it? The problem is that it’s wildly implausible that there is such an emerging customary norm. And there really is no way to claim with a straight face that this sort of thing falls under the terms of the GCs. And the problem with making aggressive claims about customary norms is that IHL really only does work if people agree to make it work. The worst thing that could happen is to have countries not even pay IHL lip service. But this all gets to the really, really hard but fundamental question of international law: enforcement. I was piqued by you originally using the term “legislation” just because the way we think about legislation, there is usually an executive to enforce it. That’s part of what makes it “law.” But there is no such thing in international law, and given how overwhelmingly powerful states continue to be, there won’t be in my lifetime. I love the idea of international law, but this is what makes it so slippery and difficult and frustrating.
