Watch: Benjamin Netanyahu Stays Silent for 45 Seconds to Show 'Deafening Silence' From U.N. on Iran's Vow to Destroy Israel

Israeli Prime Minister excoriated the United Nations for its "obsessive bashing of Israel" and "deafening silence" in the face of Iran's vows to destroy his country in a speech before the U.N. General Assembly Thursday.

"Seventy years after the murder of 6 million Jews, Iran's rulers promise to destroy my country, murder my people, and the response from this body, the response from nearly every one of the governments represented here has been absolutely nothing. Utter silence. Deafening silence," Netanyahu said.

He then held a 45-second silence before speaking starkly about the Iran nuclear deal.

“Ladies and gentlemen, perhaps you can understand Israel is not joining you in celebrating this deal,” Netanyahu said. “Perhaps if Iran’s rulers were working to destroy your country, perhaps you would seem less enthusiastic about the deal.”

Netanyahu noted that it is not easy to stand against an agreement the strongest world powers support, but said he is compelled to defend his people.

He talked about Iran's funding and associations with terrorist cells across the world.

"This deal will treat Iran like a normal country even if it acts like a dark theocracy," the prime minister said.

He also implored the U.N. to closely watch Iran, saying, "Make sure Iran’s violations aren’t swept under the Persian rug."

Speaking the day after Palestinian President Mahmoud Abbas declared that his people no longer recognizes the Oslo Accords, Netanyahu urged Abbas to resume peace negotiations.

"I am ready to immediately resume negotiations with Palestinians without preconditions," he said.

But despite public disagreements with the U.S. regarding the Iran deal, Netanyahu said, "The alliance between Israel and the United States is unshakable."
