What happens if the Egyptians say no? What happens if the Palestinians say no? Does Israel do what it did in the North and destroy the entirety of Rafah like it did in Gaza City and Khan Younis? There are 1.4 million people living there, the casualties will be in the hundreds of thousands.

The US is telling Israel not to do this.
The UK is saying not to do this.
The EU is saying not to do this.
Israel's closest allies and the world are telling Israel not to do this.
