entrenching the injustice of the violent dispossession of the Palestinian people
An awful lot of whom were trying to kill and/or dispossess the Israelis who had bought the land that they were farming. Go back and read more of the events of 1948 - the UN voted for the partition and the Arabs immediately attacked - goaded into action by the mullahs and political leaders who, needless to say, stayed far away from the front line.
Yes, that isn't an excuse but your mindset seems to forget that Israel are (or were, less so now) surrounded by countries that advocate for their utter destruction and the death of all Israelis. It's understandable how they now have a hair trigger, especially as "Mr Security" (Netanyahu) has failed so uttely in his responsibility to keep people safe.
I abhor completely what Netanyahus government is doing in Gaza and look forward to him going on trial as a war criminal. And alongside him in the dock should be the Hamas leadership - most of whom don't live in Gaza at all but live in comfort elsewhere.
As to a One State solution - do you think that Israel will willing give citizenship to people who have the express goal of destroying Israel? If you think that's viable then I have a bridge in the Nevada desert to sell you. Listen to some of the comms intercepts from that Hamas terrorists who joke about playing football with the severed heads of people, including children and try to work out how they will become peaceful, legal, productive members of a One State system. The IRA, while still being a bunch of murderous thugs funded by the US, *never* descended to those depths.
The Good Friday agreement only came about because the (aging) leaders of the IRA realised that they were never going to get a solution based on violence. Do you think that'll work in Israel? With terrorists who don't fear death because "they'll go to heaven if they die in jihad"?
