More than 70 leading UK Jewish writers and activists condemn Israel

We the undersigned are all of Jewish origin. When we see the dead and bloodied bodies of young children, the cutting off of water, electricity and food, we are reminded of the siege of the Warsaw Ghetto. When Dov Weisglass, an adviser to the Israeli prime minister, Ehud Olmert, talked of putting Gazans "on a diet" and the deputy defence minister, Matan Vilnai, talked about the Palestinians experiencing "a bigger shoah" (holocaust), this reminds us of Governor General Hans Frank in Nazi-occupied Poland, who spoke of "death by hunger".

The real reason for the attack on Gaza is that Israel is only willing to deal with Palestinian quislings. The main crime of Hamas is not terrorism but its refusal to accept becoming a pawn in the hands of the Israeli occupation regime in Palestine.

The decision last month by the EU council to upgrade relations with Israel, without any specific conditions on human rights, has encouraged further Israeli aggression. The time for appeasing Israel is long past. As a first step, Britain must withdraw the British ambassador to Israel and, as with apartheid South Africa, embark on a programme of boycott, divestment and sanctions.

The Israeli government quotes above show that Israeli government officials are now using the language of the Nazis and are aware that what they are doing is a holocaust. The US has done the Israelis no favor by supporting the country unconditionally. If Israel had been forced to face the consequences of its actions, it might not have reached this place.

Of course, the same could be said for the US.
