Israel literally told Gazans to go to Rafah to be safe. They said it was a safe zone.

And the IDF was operating elsewhere, not entering Rafah at the time.

Now they’re supposed to leave Rafah.

Yes, that’s how it works. It’s like how sometimes during road construction, the construction crew might route you into a different traffic lane. Doesn’t mean that lane will remain safe to drive on forever.

You might ask where Israel thinks Gazans are supposed to go. The answer is- nowhere. They’re supposed to die.

Now this is just plain false, since it doesn’t look like you actually bothered reading any details about it. Israel did in fact tell them where to go.
