TEL AVIV, Israel — As the first phase of the fragile Israel-Hamas ceasefire agreement nears completion, Israel is mulling its next steps against the backdrop of President Donald Trump’s repeated threats to unleash “hell” unless all the hostages are released.

Fox News Digital spoke to Israeli military experts to see how they viewed what would be in store for Hamas if the ceasefire deal collapses.

“The only alternative is the resumption of the war in Gaza with all the forces that can be allocated,” Maj. Gen. Yaakov Amidror (res.), a former Israeli National Security Council chief and currently a fellow at the Washington-based JINSA think tank, told Fox News Digital.

“Because we have a ceasefire in Lebanon, we can use huge forces inside Gaza to end Hamas. This is one of the reasons why Hamas didn’t break the truce until now, they understand the alternative is a full-blown war for which they are not ready,” he added.

“In terms of Hamas’s long-range missiles, the current capabilities are minor, if at all. Mid-range was probably reduced to approximately less than 100 total, and for short-range capabilities such as mortars and drones, it’s hard to estimate,” he told Fox News Digital.

Hayman agrees that “all hell” might entail President Donald Trump giving carte blanche to Israel to use 2,000-pound bombs or greater leeway to demolish swaths of territory using bulldozers and other heavy machinery to prevent Hamas from regenerating.

Israel might also change its fighting strategy to ensure Hamas is no longer able to regroup by retaking territory evacuated by troops in Gaza, according to Brig. Gen. Yossi Kuperwasser (res.), a former head of research in the IDF’s Military Intelligence Directorate.

“Israel could mount an attack in a different way than we saw till now. Instead of taking control of areas and then leaving them, we would keep control, minimizing Hamas’s ability to rule over the population in Gaza and thus its ability to survive,” he told Fox News Digital.

The long-term presence of Israeli boots on the ground would likely be a precondition for actualizing Trump’s vow to “take over” and transform Gaza into the “Riviera of the Middle East,” an assertion Trump made alongside Netanyahu at the White House on Feb. 4.

Meir Ben Shabbat, head of the Misgav Institute for National Security & Zionist Strategy and former head of the Israeli National Security Council, told Fox News Digital that Israel must push for “the collapse of Hamas rule, the demilitarization of Gaza and the creation of conditions to prevent this area from posing a threat to the security of Israeli citizens.”

He said these conditions are “essential to ensure that this round of fighting will be the last,” he added. “To achieve this, Israel will have to resume fighting at a time that suits it.”

On Sunday, Netanyahu informed special envoy Steve Witkoff during a meeting that he would convene the Security Cabinet on Monday to discuss phase 2 of the agreement.
