Why Israel's 'seruvniks' say enough is enough

It is said that in the first few years of the Israeli occupation of the West Bank and Gaza Strip, no one seriously thought of holding on to these territories forever. It was at the time widely assumed, that these newly conquered lands were to be handed back to the Arabs as part of a peace agreement. I don't remember those days.
I was raised in a different Israel. In my Israel the small fundamentalist group of Jewish settlers has always enjoyed more political power than their relative share in the Israeli population. In my Israel both left-wing and right-wing governments enabled the colonialisation of these occupied Palestinian lands. My Israel paid, and is still paying, a heavy moral price for ruling another nation by the force of the sword. My Israel, built on the founding values of humanism, pluralism and democracy is being lost.
