I don't think your misread it, but maybe you missed the context of it. Or perhaps I wasn't clear about the context. But I'm happy to clarify.
That paragraph references the sections above it. Someone else has claimed that Israel was justified in purely punitive attacks. I didn't say their attacks were purely punitive, I merely said they weren't justified in carrying out purely punitive attacks. It was a response to someone else's comments, not a condemnation of my own.
I've called them war crimes, and I believe they are. I think it's possible they violate the non-reciprocity portion of the laws of armed conflict (meaning I think it's possible they are purely punitive), but I'm not sure. I am certain enough to satisfy myself, however, that the Israeli attacks would not meet the threshold of a proportional proportionality analysis to be justified and for that reason I call them war crimes. But whether they are purely punitive or whether Israel simply doesn't care about the Palestinian civilians I can't say. The ICC is looking into that and in generally I believe the ICC does an excellent job in investigations and manages to remain unbiased, so I'll happily accept whatever timing they reach if they declare the attacks didn't violate non-reciprocity.
