If we judge from history, what they need now is some sort of civil war.
A civil war is the absolute worst thing that can happen now as that will only bring unimaginable misery and horror to those who are already suffering on all sides of this conflict. Those who stand to profit the most, both politically and economically, will stand clear while shouting the loudest as usual while the most vulnerable and least inclined to commit violence will get caught in the fire.
On the other hand, is there any other realistic scenario where Hamas is replaced by a peaceful party? Or even Hamas being transformed into a peaceful party ? I'd love to hear a realistic one.
Yes: the casualties mount until unconditional surrender becomes their best option.
No, that was not supposed to be a pleasant statement to read.
Most likely answer is a big mess, other militant groups and tribes(hamulut) fighting for control. kind like a civil war.And than who ever wins, you got a new terrorist organization. Hopefully we get one that is willing to work with Israel. But we might not.
But a civil war with the purpose of peace, by peaceful citizens ? Maybe that'll work.
