dingalong - here are my answers.
"are you in favour of the settlements in the west bank ?" No.
"Which borders are acceptable to you ? Pre 1967 or after ?" Pre 1967 is essential otherwise it is not a two state solution.
"If Hamas's military wing renounced violence like the IRA would you work with them if like they they agreed to Israel's right to exist within the pre 1967 borders?" Yes, it would be wonderful if they renounced violence and accepted peace with Israel's right to exist within pre 1967 borders.
"Would you grant a right to return for all Palestinians exiled ?( In a similar way to right of Jewish people to move to Israel)" If all Palestinians moved to democratic Israel, it would soon be an overwhelming Arab Muslim state and Jews would be in a minority. As a democracy it would no longer be a Jewish state serving the interests of the nation. We already have 49 Muslim majority states in the world but only one for the Jewish nation. All countries in the world have criteria for determining who can be a citizen (e.g. if you have British parents you are prioritised over non-British). Please be aware that there are 1.6 million Israeli Arabs with full citizenship in the present state of Israel, whilst Gaza is a Jew free zone.
"In every society there are a few fundamentalists so the Irish process would have been derailed due to a few splinter groups. Could you accept these might not be acting in people's name or with their support and not let it derail a peace agreement ?" Absobloominlutely. But Hamas is not a splinter group. It is the elected government of Gaza and all native opponents have been executed. There is nobody else in Gaza for Israel to negotiate with. I hope that progress can be made between Israel and the West Bank government. A peaceful independent Palestinian state in the West Bank would be wonderful.
"If it was the other way around and large amounts of Israeli civilians were being killed, and their cities razed to the ground, their hospitals destroyed, their people purposely starved, their civil rights removed I'd be supporting Israel" I am glad to hear that your motives are compassionate rather than partisan. I personally feel that putting your support behind the apparent underdog misses much of the rights and wrongs of the situation, much of the causes and a whole lot of misapplied blame.
