There's been quite a bit of talk about the possibility that Israel intends to purge Gaza, perhaps by driving the population into Egypt -- which says they're prepared "to sacrifice millions" to prevent having to accept the Gazans -- or in some other manner.
I don't know if they're intending that or not, although I notice that they're getting a lot of heat for it compared to the President of Syria, who expelled 14 million citizens who didn't get along with the government. In addition to that, though, there's some missing context: this is very much a two-way street. The Islamic world has been ethnically cleansing itself of Jews since Israel was founded in 1948; some having, prior to that, collaborated with the Nazi movement on the subject.*
One of the harder lessons in life is that there are things you can't fix. Without endorsing ethnic cleansing, I would suggest that the reason this conflict has drug on for more than seventy years is that people keep trying to put it in a bottle. Ceasefires, peace processes, and all that are well-intentioned, but they lead to generations of people living poor in 'refugee camps' that never go away -- surrounded and governed by militants who execute oppression towards them while planning terrorism abroad.
Those Syrian refugees are better off in Germany than they ever were in Syria, and certainly better off than if they'd stayed to fight for ten more years. A happier future doesn't run through diplomacy, but victory: it's time for American officials to take their hands off the wheel, and let this sort itself out. Both sides really want the same thing: they hate each other and want to be separate. What they have to work out is something that can only be worked out one way. Peace will be possible once they've had their fill of war, and not because someone put a lid on the conflict while both sides felt like they could still have won more if only the fight had kept going.
