Support is mounting for U.S. President Donald Trump’s newly announced Gaza peace proposal, with key voices in Israel and beyond urging Hamas to accept the plan.

On Monday, Israeli President Isaac Herzog publicly threw his weight behind the initiative, praising Prime Minister Benjamin Netanyahu for working with Washington on the proposal.

In a message posted on X (formerly Twitter), Herzog urged the international community to pressure Hamas into compliance.

The proposal demands that the militant Hamas group effectively surrender in return for uncertain gains. But if it rejects the deal, the U.S. could give Israel an even freer hand to continue its punishing campaign in the already devastated territory.

‎Under the proposal, the militant group would have to disarm in return for an end to fighting, humanitarian aid for Palestinians, and the promise of reconstruction in Gaza all desperately hoped for by its population.

According to Isaac Herzog, the world must unite to ensure the militant group agrees to the deal, which he described as a step toward “a future of hope for the peoples of the region.”

Backing also came from the Tikva Forum, a group representing families of hostages and fallen Israeli soldiers. Known for their tough stance, the families welcomed the plan, noting that it guarantees the release of captives and the return of the bodies of the dead for burial in Israel.

“The living will return to their families, and the dead will be returned for a dignified burial,” the forum stated. They further stressed that the proposal would put an end to Hamas’s rule in Gaza and neutralize its threat to Israel.

The endorsements add to a growing wave of international support. Already, France, Italy, and other European partners have expressed approval, seeing the plan as a pathway to a permanent ceasefire, freedom for hostages, and improved humanitarian access for civilians in Gaza.

While the proposal has sparked optimism, analysts note that its success will depend largely on whether Hamas agrees to its terms a decision that could determine the next phase of the long-running conflict.
