MRS Summerfield (Letters, August 9) is correct. The Israeli Government drops leaflets, makes phone calls and sends warning rockets – whatever they may be – to the people of Gaza.

But what is not very easy to explain to the world at large is why they have blown apart three young boys taking shelter from missiles on a beach, or the massacre of innocent women and children in a UN safe area.

Hamas is not innocent in all this, but the Israeli response is disproportionate and may be in breach of Article 3 of the Geneva Convention.

Let’s hope that Cameron and Obama can find the moral strength to stand up and say as much.

Finally, Mrs Summerfield comments that “there is no holocaust”. Well, the Israelis are certainly imposing a ghetto principle on Gaza. Most Polish Jews will explain to you about Warsaw, and we all know what despicable acts that led to.
