I am hoping beyond hope that that does not happen. I do wonder if they will delay due to the change in tone from John Kirby but I honestly can't see it as there has been no stopping Israel since they began this particular intensive phase. I can't see them being reigned back in.
As Israeli forces have previously repeatedly targeted areas that they originally claimed were "safe" and numerous Palestinian people stating before now that they feared Rafah would be the end of them is haunting.
I do suspect that this is an attempt to force Egypt to allow people in. (Which I cannot see happening)
