I do worry when the first recourse of Israeli self defence is to label all criticism of its actions "anti-semitic". Just as Robert Mugabe calls all criticism of his regime "racist" and colonialist". It is more important for those sympathetic towards Israel to crticise it than its enemies, especially now. And Israelis should understand that sympathies can be stretched and frayed, they are not unconditional.
Yes, the obvious association of Israel with Hitler in this cartoon seems a bit crass. But a point is being made and cartoons are more often slegehammers than scalpels. I personally disagree with suggesting this is comparable with a genocide or the holocaust. But I see parallels between Gaza and the Warsaw ghetto.
And I fear what Israel is doing to itself more than to Gaza. keep to the Fen Causeway
Still, it's a funny cartoon. Peak oil is not an energy crisis. It is a liquid fuel crisis.
