There's been the explanation from Israeli officials that their bombing raids where civilians have been killed were efforts to weaken Hamas' ability to launch rockets. That doesn't seem to be panning out.
One obvious and apparent effect of these tragic bombings is the increase in animosity from Arabs toward Israel and their aims and an increased likelihood of some sort of retaliation. Also there will likely not be the political distancing of Palestinians from Hamas and the directing of residents toward supporting moderate politicians like Abbas which was undoubtedly one part of the strategy behind the Gaza air strikes.
Militarily and politically, the Israeli offensive is already mired in an escalating failure in their inability to realize their most basic objectives; isolation of Hamas and a cessation of missile and other attacks.
It's becoming less and less possible for Israel to argue that these strikes where hundreds of innocent civilians have been killed are a necessary or productive use of force, especially since these attacks where civilians are known to be present are illegal under international law without any 'imminent' danger to Israel . . .
