Israel will need to take over all of Gaza to meet its war objectives, a senior reserve Israeli general said, as the United States moves ahead with plans to assemble a multinational stabilization force that is not expected to deploy in Hamas-controlled areas.

Brig. Gen. (res.) Amir Avivi, a former deputy commander of the Israel Defense Forces (IDF)’s Gaza Division, said the military aims of the war — including the disarmament of Hamas — cannot be achieved without moving into the remaining parts of the enclave still held by the Palestinian terrorist group. 

“There is no way to reach the goals of war without conquering Gaza,” Avivi told The Algemeiner. 

“Ninety-nine point nine percent, the IDF is going to be the [party] that will dismantle Hamas,” Avivi said, noting that the Trump administration’s International Stabilization Force is expected to deploy only in Israeli-held areas and avoid confronting Hamas directly.

A decisive campaign could be completed in a month or two, Avivi said, because the constraints that slowed earlier phases of the war — most notably the presence of Israeli hostages in Hamas-held areas — no longer apply. The IDF could expand from its current 53 percent control of Gaza to 75 percent in “as little as a week,” he said. 

With the Israeli security cabinet focused on Iran, no final decision has been taken yet on the next phase in Gaza, Avivi said. The government is likely to give Hamas “a month or two” to see if a confrontation with Iran materializes before moving to conclude the campaign in Gaza.

Avivi is the founder and chairman of the Israel Defense and Security Forum, known in Hebrew as Habitchonistim, a hawkish group of former senior officers and security officials that has consistently pushed for maximal military objectives in Gaza and opposed negotiated compromises with Hamas.

According to US and Israeli officials, the stabilization force is expected to begin deploying in southern Gaza, starting in Rafah, and expand gradually as conditions allow. The force is intended to help establish governance and security conditions in cleared areas, rather than conduct combat operations or forcibly disarm armed groups. Its commander, US Army Major General Jasper Jeffers, has said five countries — Indonesia, Morocco, Kazakhstan, Kosovo, and Albania — have committed personnel so far, with longer-term planning envisioning a significantly larger deployment of up to 20,000 troops and police focused on policing, security coordination and aid facilitation.

The Guardian reported last week that US contracting documents describe plans for a 350-acre military base in Gaza designed to support 5,000 people that will include watchtowers, bunkers, and training facilities. A US official declined to discuss the contract and reiterated that Washington does not plan to deploy US combat troops to the enclave.

The stabilization effort was formally launched in Washington on Thursday, when US President Donald Trump convened the inaugural meeting of his Board of Peace. Trump said participating countries had pledged roughly $7 billion as an initial down payment for Gaza reconstruction, while making clear that broader rebuilding would be conditioned on Hamas’s disarmament.

US officials and regional partners acknowledge that demilitarization would likely be a long-term process and that reconstruction carries political risk. Some donor states have privately raised concerns about funding rebuilding efforts only for Israel to return to large-scale military operations. 

Avivi said Israel’s takeover of the enclave would be followed by a technically complex cleanup phase focused on dismantling tunnels and weapons stockpiles. “The whole area is full of tunnels and munitions,” he said. “Finding and destroying them is complicated. That part takes time.” 

A strategy gaining traction in the US framework would see Gaza divided into two zones, a Hamas-free “green zone,” where reconstruction and alternative civilian governance could begin, and a “red zone” comprising areas still held by Hamas. 

Former Israeli national security adviser Yaakov Amidror said that while he understands the logic behind the approach, it carries risks. Rebuilding Gaza first in IDF-controlled areas, he said, could allow Hamas to survive politically and militarily elsewhere in the enclave.

“If you build only where the IDF controls, you are effectively telling Hamas: you can stay in Gaza,” Amidror told The Algemeiner.

Avivi agreed that reconstruction would not begin “until they lay down their weapons,” warning that doing otherwise would amount to tolerating Hamas’s continued presence.

The Israeli general pointed to the period leading up to the October ceasefire, when Israeli forces advanced deep into Gaza City and took control of roughly half the city, as an example of how Hamas responds when the IDF enters its core terrain. He said Israel’s subsequent pullback to about 53 percent control of the Gaza Strip was driven by hostage negotiations rather than operational limits.

“It’s going to happen the nice way or the hard way,” Avivi said. “The hard way is the IDF. So, they either lay down the weapons and get out of Gaza or the IDF will go in and impose demilitarization.”

Amidror rejected arguments that Hamas is emerging from the war in a stronger position because of potential involvement by countries such as Qatar or Turkey, calling the claim disconnected from current military realities.

“It’s a stupid argument because Hamas is surrounded on all sides by the IDF — 300 degrees by land and 60 degrees by sea, which the IDF also controls,” Amidror told The Algemeiner. The terrorist group, he explained, cannot receive weapons because it has no land border with Egypt, cannot manufacture arms because Israel has destroyed its production infrastructure, and is surrounded on all sides by Israeli forces.

“The most it can do is fire a missile, probably once every six months,” Amidror said.
