Israeli Prime Minister Benjamin Netanyahu told the UN General Assembly on Friday that Israel “must finish the job” against Hamas in Gaza, giving a defiant UN speech despite growing international isolation over his refusal to end the devastating war in Gaza.

He spoke after dozens of delegates from multiple nations walked out of the UN General Assembly hall en masse on Friday as he prepared to speak.

As the Israeli leader spoke, unintelligible shouts echoed around the hall.

The US delegation, which has backed Netanyahu in his campaign against Hamas, stayed put.

Applause rang out in other quarters as he began his speech.

As he has often in the past, Netanyahu held up a visual aid — a map of the region titled “THE CURSE.”

He marked it up with a large marker.

Later, he pinned a QR code onto his suit jacket and held up a board with a multiple-choice question that he read to the audience.

He also frequently praised President Donald Trump, his chief ally in his political and military approach in the region.

In an “unprecedented operation,” the Israeli army will take over the mobile phones of Gaza residents and Hamas operatives and his speech will be broadcast live through the mobile devices.”

Netanyahu faces international isolation, accusations of war crimes and growing pressure to end a conflict he has continued to escalate.

Friday’s speech was his chance to push back on the international community’s biggest platform.

Netanyahu’s annual speech to the UN General Assembly is always closely watched, often protested, reliably emphatic and sometimes a venue for dramatic allegations.

But this time, the stakes are higher than ever for the Israeli leader.

In recent days, Australia, Canada, France, the United Kingdom and others announced their recognition of an independent Palestinian state.

The European Union is considering tariffs and sanctions on Israel.

The assembly this month passed a nonbinding resolution urging Israel to commit to an independent Palestinian nation, which Netanyahu has said is a non-starter.

The International Criminal Court has issued an arrest warrant accusing Netanyahu of crimes against humanity, which he denies.

And the UN’s highest court is weighing South Africa’s allegation that Israel has committed genocide in Gaza, which it vehemently refutes.

Against that backdrop, Netanyahu sounded resolute on Thursday as he boarded a plane in Israel to head for the UN’s annual meeting of top-level leaders in New York.

“I will tell our truth,” Netanyahu said. “I will condemn those leaders who, instead of condemning the murderers, rapists and burners of children, want to give them a state in the heart of Israel.”

Opposition to Netanyahu’s approach is growing

At a special session of the assembly this week, nation after nation expressed horror at the 2023 attack by Hamas militants that killed about 1,200 people in Israel, saw 251 taken hostage and triggered the war.

Many of the representatives went on to call for an immediate ceasefire in Gaza and influx of aid.

Israel’s sweeping offensive has killed more than 65,000 Palestinians in Gaza and displaced 90 per cent of its population, with an increasing number now starving.

While more than 150 countries now recognise a Palestinian state, the United States has not, providing Israel with vociferous support.

But President Donald Trump pointedly signalled on Thursday there are limits, telling reporters in Washington that he wouldn’t let Israel annex the occupied West Bank.

Israel hasn’t announced such a move, but several leading members in Netanyahu’s government have advocated doing so.

And officials recently approved a controversial settlement project that would effectively cut the West Bank in two, a move that critics say could doom chances for a Palestinian state.

Trump and Netanyahu are scheduled to meet during his visit.

Back in the Mideast, in addition to the phone takeover, Israel said on Friday it would broadcast Netanyahu’s speech from southern Israel into Gaza, carrying his remarks across the border to Palestinians in the besieged enclave.

His office “instructed civilian groups in cooperation with the army to place loudspeakers on trucks on the Israeli side of the border,” it said in a statement, noting that the broadcasts would be arranged so they would not endanger soldiers.

Palestinians had their UN say the day before

Netanyahu was preceded on Thursday by Palestinian leader Mahmoud Abbas, who addressed the General Assembly via video, since the US denied him a visa.

He welcomed the announcements of recognition but said the world needs to do more to make statehood happen.

“The time has come for the international community to do right by the Palestinian people” and help them realize “their legitimate rights to be rid of the occupation and to not remain a hostage to the temperament of Israeli politics,” he said.

Abbas leads the internationally recognised Palestinian Authority, which administers portions of the West Bank.

Hamas won legislative elections in Gaza in 2006 before seizing control from Abbas’ forces the following year.

Israel captured the West Bank, east Jerusalem and the Gaza Strip in the 1967 Mideast war, then withdrew from Gaza in 2005.

The Palestinians want all three territories to form their envisioned state, part of a “two-state solution” that the international community has embraced for decades.

Netanyahu opposes it robustly, maintaining that creating a Palestinian state would reward Hamas.

“This will not happen,” he said at the airport on Thursday.
