Oct 6th situation was tenable as a starting point.
There needed to be international pressure on expanding settlements. Obama failed.
Hamas needed to stop its suicide and missile attacks. Oct 7 attack in particular was irresponsible.
The Jews are not leaving the Levant and neither are the Arabs. That is the starting point, whether one has grievances re the establishment of Israel or not.
Like we cannot expect "white" Australia to go pack up and leave. The indigenous community is not demanding that and they are not launching violent attacks.
