This is devastating. And amidst so much debate over Israel's right to defend itself, I feel it's getting lost that this military campaign is only a success if measured by a set of goals even most Zionists would not recognize as productive.
Will it make Israel safer? No, undoubtedly the war has cost international standing, strained the US-Israel relationship, and will inevitably radicalize far more extremists than are killed.
Will it continue the right-ward shift of Israeli policy? Does it cut off avenues for peace and reconciliation and foster militant Israeli nationalism? Yes.
This campaign is only a success if the primary objective is the eventual capture of the entire region at the cost of Israel's safety (and the safety of Jews around the world) and Israel's international standing. By any more conventional aims, it is an unmitigated disaster.
