The window of opportunity for a ceasefire in Gaza is closing fast, writes Judah Grunstein:
Any further, by which I mean Israel expanding its operation to enter the cities of Gaza, and the logic of war dictates that the fight has to go on to the bitter end. Israel can not afford to retreat under fire, and Hamas can not afford to let an Israeli penetration into its urban strongholds go unpunished. In other words, this is the point of no return beyond which both sides must commit to a total, if asymmetric, war, with all the wild card scenarios that presents.
