The Generals’ Plan was presented to the parliament last month by a group of retired generals and high-ranking officers, according to publicly available minutes. Since then, officials from the prime minister’s office called seeking more details, according to its chief architect, Giora Eiland, a former head of the National Security Council.

Israeli media reported that Netanyahu told a closed parliamentary defense committee session that he was considering the plan.

Eiland said the only way to stop Hamas and bring an end to the yearlong war is to prevent its access to aid.

“They will either have to surrender or to starve,” Eiland said. “It doesn’t necessarily mean that we’re going to kill every person,” he said. “It will not be necessary. People will not be able to live there (the north). The water will dry up.”

When asked if the evacuation orders in northern Gaza marked the first stages of the “Generals’ Plan,” Israeli military spokesperson Lt. Col. Nadav Shoshani said no.

“We have not received a plan like that,” he added.

But one official with knowledge of the matter said parts of the plan are already being implemented, without specifying which parts. A second official, who is Israeli, said Netanyahu “had read and studied” the plan, “like many plans that have reached him throughout the war,” but didn’t say whether any of it had been adopted. The officials spoke on condition of anonymity, because the plan isn’t supposed to be discussed publicly.

On Sunday, Israel launched an offensive against Hamas fighters in the Jabaliya refugee camp north of the city. No trucks of food, water or medicine have entered the north since Sept. 30, according to the U.N. and the website of the Israeli military agency overseeing humanitarian aid crossings.
