Mr Netanyahu has publicly rejected the US push for a future Palestinian state and insisted the offensive would continue “until complete victory”.
But Gadi Eisenkot said those advocating “absolute defeat” of Hamas were not “speaking the truth”.
The retired general’s son was killed fighting in Gaza.
He also said Mr Netanyahu shared “sharp and clear responsibility” for failing to protect his country on 7 October and urged fresh elections, saying there was “no trust” in Israel’s current leadership. (BBC)
