Chaps, don't kid yourselves that this has anything to do with Israel - it's a problem all right and it needs sorting out, but it's not the cause of any of the troubles we are facing. The Palestinians have been treated badly by many people, Jordan has much to answer for, and Muslims all over the world have suffered terribly, usually at the hands of other Muslims, but you won't hear any hatred preached against them in your local mosque - that particular honor seems to be reserved for Jews and the west in general.
Also don't kid yourselves that we are fighting a war against terror, or even against al qaeda [whatever that is] - the truth is [tho we are too politically correct to say it], is that we are fighting fundamentalist Islam. The Saudis have been funding extremists for years, they have basically exported a civil war, and we now have a worldwide insurgency. The extremists want to re-establish the Muslim domination of much of the world, under a Taliban style rule. The Madrid train bombers spoke of 'settling old accounts with Crusader Spain', in other words they're looking back to 1492 when the last Muslim stronghold in Spain, fell to the Catholic King Ferdinand. They still haven't forgotten it.
This is much more than a struggle about a bit of land in Israel/Palestine, it's about a fascist expansionist totalitarian creed, similar to Nazism or communism but probably more dangerous.
