Israeli Prime Minister Benjamin Netanyahu told the UN General Assembly that "Iran was rapidly developing a massive nuclear weapons program and a massive ballistic missile program."
"These were meant not only to destroy Israel, they were meant also to threaten the United States and blackmail nations everywhere," Netanyahu said in his Friday address.
"We devastated Iran's atomic weapons and ballistic missiles programs."
Netanyahu said Israel's 12-day war against Iran "will go down in the annals of military history. Our pilots neutralized Iran's missile defenses and took control of the skies over Tehran."
He thanked President Donald Trump "for his bold and decisive action", referring to the US strikes against Iran's nuclear facilities.

However, he added, "we must remain vigilant. We must remain absolutely clear minded and vigilant. We must not allow Iran to rebuild its military nuclear capacities, Iran stockpiles of enriched uranium. These stockpiles must be eliminated."
"Tomorrow, UN Security Council sanctions on Iran must be snapped back," Netanyahu said ahead of looming return of UN sanctions against Iran as part of the so-called snapback mechanism.
"Israel's victories over the Iranian terror axis have opened up possibilities for peace, that were unthinkable," Netanyahu said.
'Iranians will regain their freedom'
"Many of those who wage war on Israel today will be gone tomorrow. Brave peacemakers will take their place and nowhere, nowhere will this be more true than in Iran," Netanyahu said.
"The long-suffering Iranian people will regain their freedom, they will make Iran great again. And our two ancient peoples, our two ancient peoples, the people of Israel and the people of Iran, will restore a friendship that will benefit the entire world," he added.
