I agree with you. They have hinted at this several times now and then it's been delayed. There's also been a lot of talk (social media, not referenced at all) about potential ICC warrants for Netanyahu and behind the scenes wrangling and threats to stop this happening, perhaps with some kind of trade-off in delaying or scaling down the assault on Rafah.

If it happens, I dread to think of the results but the apartheid state surely thinks, "Look at all the inhuman barbaric shit we've done already and faced pretty much no consequences; we can do anything". I fear it will make Sabra and Shatila look like a pillow fight.
