Just days before President Trump will decide whether to pull out of the Iran nuclear deal, Netanyahu presented what he called "proof" of a secret Iranian nuclear weapons program.
"After seven years of the term of the agreement expires, Iran will be able to move on and acquire nuclear weapons".
The US official underlined the growing concern surrounding Iran's attempt to obtain nuclear weapons.
Mr Netanyahu, standing in front of a large LED screen, said Israel, in an intelligence coup, had covertly obtained 55,000 records and 55,000 files stored on 183 CDs relating to an Iranian bid to secretly pursue nuclear weapons activity. He said the material was gathered from a vaulted Iranian facility a few weeks ago "in a great intelligence achievement". "The United States is with Israel in this fight", The Washington Post quoted Pompeo as saying.
Trump's new secretary of state, Mike Pompeo, made it clear while visiting Jerusalem on Sunday that the U.S. leader would insist on changes to the accord. "That is not acceptable", Trump told reporters at a joint press conference with Nigerian President Muhammadu Buhari. Even if you ignore the Mullahs' decades of terrorist sponsorship, hostage-taking, and lies, you have to know that they violated the agreement nearly as soon as they signed it. Those well-known concerns were the reason why the worldwide community negotiated an agreement to limit Iran's nuclear program and subject it to intrusive global inspections.
Netanyahu met in Tel Aviv on Sunday with new U.S. Secretary of State Mike Pompeo and both men talked tough about Iran.
Speaking to reporters Monday, Trump touched on the possibility of ending the Iran deal in May.
"We've known for years that Iran has had a secret nuclear weapons program", he added, presenting slides of what he called Iran's secret nuke files.
In the Rose Garden after Netanyahu's presentation, President Trump said that while he thinks the "horrible agreement" with Iran is unacceptable, he is open to negotiating a new deal.
Iran stopped producing 20 percent enriched uranium and gave up the majority of its stockpile as part of the agreement with the United States, Britain, France, Germany, China and Russian Federation.
Netanyahu alleged Iran's leaders repeatedly lied about their nuclear ambitions.
Government outposts were attacked in missile strikes in northern Syria overnight, according to the Associated Press, killing dozens of pro-government fighters in the area - majority Iranians.
Netanyahu warned Iran's leaders "not to test Israel's resolve".
Unveiling a Powerpoint presentation on "Iranian lies and deceptions" in English, Netanyahu presented graphics and aerial photographs allegedly proving the existence of an Iranian plan entitled Amad aimed at developing nuclear missiles.
Meanwhile, U.S. crude production jumped 260,000 barrels per day (bpd) to 10.26 million bpd in February, the highest on record, the Energy Information Administration said in a monthly report on Monday.
