What Uri Dromi says about Hamas is pure and poisonous Israeli propaganda (This Hamas hallucination, 23 January). In every respect his article is almost the exact opposite of the truth. Dromi claims that: "The Orwellian mindset of the organisation is as much a barrier to peace as the rockets it fires." But it is the newspeak of Israeli propagandists like Dromi that is truly Orwellian.

Over the last four weeks the powerful Israeli propaganda machine has been churning out lie after lie about Hamas in order to excuse its own inexcusable onslaught. Israel stopped journalists going into Gaza, preventing any independent reporting on the war crimes its forces were committing. Truth is usually the first casualty in war. Gaza was not even a war in the conventional sense of the word; it was one-sided carnage.

Here are some of the facts Dromi ignores or wilfully misrepresents. First, Hamas is the democratically elected government of the Palestinian people, not the corrupt regime led by Mahmoud Abbas. Second, Hamas spokesmen have repeatedly declared their readiness for a long-term ceasefire. Khalid Mish'al recently did so on these pages (Comment, 6 January). Third, Hamas has a solid record of observing ceasefires, while Israel has a consistent record of sabotaging them. Fourth, even during the ceasefire Israel did not lift its economic blockade of the 1.5 million inhabitants of Gaza, a form of collective punishment forbidden by international law. Fifth, the offensive unleashed in Gaza was illegal, immoral and unnecessary. If all Israel wanted was to stop rocket attacks from Gaza, all it had to do was to observe the ceasefire brokered by Egypt in June 2008.
