The Shabak is also against the harbor in Gaza, but for a different reason: they fear that a Palestinian harbor in Gaza would erode the standing of Mahmoud Abbas or his replacement, and permanently dismantle the separation between Gaza and the PA.
Unless the Turks give up on their Gaza harbor principle, this debate is not likely to just fade away. Gazans are paying for their terrible mistake of voting Hamas into power ten years ago, Hamas is there to stay — but can Israel afford to let those Gazan civilians continue to suffer? Perhaps now would be a good time to put into action one of those programs that advocate paying local Arabs to immigrate to better places. At this point it probably won’t require that much money.
