BBC UN correspondent Barbara Plett-Usher says the US's Western allies shared Washington's concerns but have warned against reopening the deal in order to address them.
In recent years, Netanyahu has regularly and often complained often about the United Nations and America's diminished presence in a body which regularly passes resolutions seen as anti-Israeli.
"After 70 years, the world is embracing Israel and Israel is embracing the world", he said, calling Israel "the innovation nation" for its inventions in medicine, agriculture and its philanthropy to nations beset by disasters and crucial intelligence for nations battling terrorism.
He offered no path toward making that future a reality. The U.S. could give Iran 90 days to meet certain new conditions, including opening military sites to global inspectors, according to a memo obtained by Foreign Policy.
Trump returned to the theme in his address.
"It has turned a wealthy country with a rich history and culture into an economically depleted rogue state whose chief exports are violence, bloodshed and chaos", he said, repeating a litany of oft-spoken US complaints about Iran.
Barack Obama's United States administration said at the time the deal would prevent Iran from obtaining a nuclear weapon.
She said that, "it's not for one party or the other to certify this".
"In the absence of such a policy roadmap, the president's words won't change North Korea's behavior", said Frank Jannuzi, an East Asia expert and president of the Washington-based Mansfield Foundation. Please join us in sending that strong message to them.
Fears of a military confrontation are increasing.
"Reelected by a popular vote for a second presidential term in May, Rouhani was a key architect of the 2015 nuclear agreement with the United States, the European Union and other partners". "We are talking about enrichment, not building an atom bomb, even in Japan today they have enrichment, and with enrichment their power plants are receiving the needed fuel through enriched uranium". If he fails to do so, Congress could re-introduce sanctions dropped when the accord was implemented. American officials say the time isn't right for any formal diplomatic process. Rocket man is on a suicide mission for himself and for his regime.
If Trump really wanted to end the deal, he could stop waiving USA sanctions on Iran for its nuclear program on his own, which would be a "material" breach of the agreement that would effectively destroy it and allow Iran to walk away.
The comparison could reinforce Kim's view that he needs nuclear-armed, intercontinental ballistic missiles to deter the USA from attacking him, according to Mark Fitzpatrick at the International Institute for Strategic Studies.
Trump and United States officials also echo Netanyahu in their criticism of sunset provisions in the deal, which allow Iran to resume some nuclear-related activities after a few years.
The Iran deal was one of the worst and most one-sided transactions the United States has ever entered into.
Pressed on what that decision might be he said, "I will let you know".
"It was a good opportunity to meet, shake hands".
Pyongyang may be completely uninterested.
The Palestinians are keen to clarify U.S. support for a two-state solution to the stand-off with Israel, the focus of worldwide diplomacy since at least the 1990s.
Tillerson said he was surprised when Trump announced he had reached a decision. "That's a unsafe place to be". So again, if Trump pulls out, the US will take the blame.
German Chancellor Angela Merkel on Wednesday rejected Donald Trump's threatening approach.
