It will be at least a month before they can get the population out of Rafah. Israel should make sure housing and infrastructure are demolished in North Gaza, all the “refugee camps”. Make sure that there is nothing to come back to. including the imploded tunnels.
That should take a week. Return children under 13, females and males over 60.
The remaining Rafah send them to a beach area or the Gaza airport
All that stay behind are either Hamas, supporters, or Hamad.
Go in and flatten that place no matter the collateral damage.
