That is literally impossible. The Rafah crossing, the only way to go into Egypt, has been closed for days. Even if were open, it could only handle an infinitesimal fraction of the people trying to flee, let alone in the next 24 hours. The Israeli govt is fully aware of this, as is anyone with even the most basic grasp of the situation.
The biggest reason Egypt doesn't want Palestinians, beyond the general unpopularity of accepting large numbers of refugees in every country ever, is that once they leave it's extremely likely they'll never able to return. That's exactly what happened in 1948 and 1967. It's how Lebanon and Jordan wound up with millions of refugees living in permanent camps. No govt would want that. It would also be ethnic cleansing, just like it was in 48 and 67.
And collective punishment - starving an entire population and driving them from their homes - is morally indefensible, as well as a war crime.
Also, I'm probably done responding to your posts in this thread. It's not about disagreeing POVs, it's that your posts are consistently so ignorant and unserious, and you seem so uninterested in making any effort at all to become less ignorant, that they're not worth engaging with.
