Yossi Sarid writes in today’s Ha’aretz: “It is important that this much is understood from the start - no matter what happens in this war, the crossings into Gaza must open.

A million and a half human beings, most of them downcast and desperate refugees, live in the conditions of a giant jail, fertile ground for another round of bloodletting.

The fact that Hamas may have gone too far with its rockets is not the justification of the Israeli policy for the past few decades, for which it justly merits an Iraqi shoe to the face.”

I also recommend reading this article by Amira Hass.
Amira Hass is an excellent journalist, even if you happen to disagree with some of her political views. (I interviewed Amira Hass for an article about the IDF.)
