There are the disputed historical facts, the dodgy religious justifications, the 'who's David, who's Goliath?', the protests against bias and hypocrisy, one side's dog-eared trump card cry of 'anti-Semitism' , the other's retort 'the Palestinians are Semitic too!' On both sides is a feeling that the other side just cannot see the mastodon taking a dump on the carpet.
This current furore fits the established pattern: the Israeli paratrooper shoots dead the Palestinian boy throwing stones. The Palestinians cry 'see how these heartless criminals shoot children!'. The Israelis cry 'see how these vicious bastards send their own children to their deaths!' No doubt voices of reason and reconciliation are ignored on both sides. I recall the same situation on a grander scale recorded in Robert Fisk's 'Pity the Nation', where the PLO installed an anti-aircraft gun on the roof of a hospital, which was bombed forthwith. The challenge; 'you wouldn't dare!' doesn't work too well with the Israelis.
Personally I have always favoured the Palestinians. Maybe it has something to do with one of my close school friends who was an Arab, or that I remember the Sabra and Shatila massacres (be the first Israphile to shout "that was the Falangists!" and win a prize), which horrified me - one of the first times I'd seen dead bodies on the news. Whatever the original cause, the Palis are 'my team', and my sympathies usually go to them. So, all of you on the other side, feel free to have a go, but don't be obliged, as we've all heard and stated the arguments before, and it's all water off a duck's back.
My main concern with regard to the region is that Israel will do what it's been gagging to do for years: attack Iran. Nobody knows just what's inside that particular Pandora's box, but the term 'bloodbath' will no doubt be applicable.
