The talks aimed at ending the violence in Gaza are failing because there is no guarantee any ceasefire negotiated at present will last. Hamas wants a permanent ceasefire leading to the establishment of a “fully sovereign” Palestinian state. The Israeli government – particularly the more rightwing nationalistic elements – wants Hamas destroyed completely. It’s not clear these conflicting positions can be reconciled.
Insurgencies can be defeated by eliminating the insurgent militarily, or by effectively addressing the grievances that prompted them to take up arms – or a combination of both. This means continuing conflict while negotiating a peace deal in good faith.
In Northern Ireland, the British were persuaded to do both and it worked. In Palestine, Israel uses force with considerable effect – but in the absence of peacemaking, this force is counterproductive. The grievance remains unaddressed and the insurgency grows.
