For Gaza and others who stay to support Hamas. Remember the so called “LeMay leaflets” in WWII?
“We urge that you accept these consequences and begin the work of building a new, better and peace-loving Japan. You should take steps now to cease military resistance. Otherwise, we shall resolutely employ this bomb and all our other superior weapons to promptly and forcefully end the war. EVACUATE YOUR CITIES.”
The problem in this case is where can the Gazans go, unless Egypt accepts them? I doubt Egypt has the resources even if they wanted to (probably not.) The rich oil states could fund it, but will they?
