There is another right that Israel does not have: to delude its people into thinking that peace is achievable without coming to terms with the deeply entrenched Middle Eastern realities that are Hamas and Hezbollah, organizations still viewed in the US government and Congress almost exclusively through the prism of terror, but whose grassroots political movements present a far more complex, variegated picture. The logic of the Israeli offensive, if there is one, must surely be that Hamas can be so weakened as ultimately to crumble. That is also the logic of the relentless blockade that persisted during the six-month cease-fire despite Israel’s earlier commitment, as part of the deal, to opening border crossings. But such logic is flawed. Hamas is not going away.
