A ceasefire is quite doable. Hamas surrenders unconditionally. All hostages are freed immediately. Hamas leadership will be subjected to war-crimes tribunals held by the victorious Israelis. Hamas foot soldiers will become P.O.W.s and ‘de-Hamasified’ before being released. This worked pretty well the last time we won a war.
We'll have to ban Islam in Gaza. All the Hamas foot soldiers will have to convert to a new religion before we can release them.
The West is too PC to do something like this. Israel can do it but they need money and support from the U.S. to keep them afloat (including maintaining the Iron Dome).
