In its war against Hamas, Israel faces a tragic choice between two different routes to disaster | Jonathan Freedland

The Israelis' goal of destroying the enemy risks slipping further out of reach the more they pursue it

And on the eighth day, the war began anew. After a week of joy and relief for those Israeli families reunited with loved ones held hostage by Hamas, and of respite from Israeli bombardment for the people of Gaza, seven days of rolling ceasefires came to an end this morning. No more hugs, no more quiet. Instead, the war between Israel and Hamas is back on, presenting once more what moral philosophers refer to as a tragic choice" - a dilemma where there are no good options, only two different routes to disaster. In fighting Hamas, Israel faces just such a predicament - and yet there are too many, among both those who defend Israel and those who denounce it, who refuse to see that.

Start with those who believe that the massacre by Hamas of more than 1,200 Israelis on 7 October gives Israel the moral licence to respond however it sees fit, subject to almost no limitations. In this view, the horror of the October attacks, the sadism and cruelty of the killing, torture and rape, crossed every moral red line and so Israel can do whatever it takes to defeat those to blame. Not as revenge, but as prevention - to ensure that Hamas cannot make good on its vow to stage another 7 October, and another and another, until Israel is eradicated.
