Are you saying they really have no intention of going through with the eviction of Jews from Gaza? If so I believe you are seriously misreading the situation there.
It's going to take such a long time that it might stretch out into never. It will take a long time due to continuing Palestinian violence. The Gaza settlers resisting will impress Europe about how serious Israel is. If/when Israel does leave Gaza it will be done on terms favorable to Israel such as control of Gaza borders to prevent weapon's smuggling
Israel is always hoping for a miracle given the Islamization of Europe and it's Jihadist neighbors. Iran getting nuclear bombs, things get worse for Israel's continued existence. Europe is demanding that the Muslims be thrown a bone and Gaza will be it.... but over a long time period... the drama of withdrawal will be stretched out for years.
Israel is not an island. It depends on European goodwill and trade to stay afloat. You have any better suggestions than shedding Gaza? Which is a pain in the ass anyhow and not part of biblical Israel?
