As the Trump administration pushes forward with efforts to revive a nuclear agreement with Iran, Israeli Prime Minister Benjamin Netanyahu has reportedly threatened to disrupt the negotiations by targeting Iran’s key nuclear enrichment facilities, according to The New York Times, which cited officials familiar with the situation.

The disagreement over how to effectively prevent Iran from acquiring nuclear weapons has sparked heightened tensions between the U.S. and Israel. It has also prompted at least one tense phone conversation between President Donald Trump and Netanyahu, alongside several high-level meetings between American and Israeli officials in recent days.

President Trump expressed cautious optimism on Sunday, saying there could be “something good” emerging from the talks within the next two days. However, sources close to the negotiations indicated that any immediate announcement would likely be limited to a statement of shared principles, rather than detailed agreements. Key issues under discussion remain tightly guarded, centering on whether Iran will be allowed to continue uranium enrichment at any level and how to manage its stockpiles of near-weapons-grade material, either through dilution or removal from the country.

Earlier reports from The New York Times suggested that Israel had planned a military strike on Iranian nuclear sites as early as this month. However, President Trump reportedly persuaded Netanyahu to hold off, preferring to continue diplomatic efforts with Tehran. Despite this, Netanyahu has maintained pressure for unilateral military action, even without explicit U.S. support.

Israel is not directly involved in the U.S.-Iran negotiations, which adds to the friction between Netanyahu and the Trump administration. Their discord largely stems from differing assessments of how best to capitalize on Iran’s current vulnerabilities.

A White House official and an individual close to the matter told Axios that Trump warned Netanyahu during a phone call last week not to undertake any actions that could jeopardize ongoing negotiations. The U.S. administration has grown increasingly concerned in recent weeks that Israel might unilaterally strike Iran’s nuclear facilities or take other disruptive steps.

Officials revealed that Israel is preparing for a rapid strike should diplomatic talks collapse in the coming weeks. One source told Axios that Israel believes its window to conduct a successful operation may close soon. Some U.S. officials worry Netanyahu might proceed without a green light from the White House.

During the Thursday call, Trump emphasized that he “doesn’t want anything to impede” a diplomatic resolution, according to the White House. He urged Netanyahu not to escalate tensions amid efforts to resolve the issue peacefully. While Trump stressed that military options remain available, he insisted on prioritizing diplomacy.

The call occurred shortly after a shooting in Washington that claimed the lives of two Israeli embassy staffers, adding a somber backdrop to the discussion.

On Sunday, U.S. Secretary of Homeland Security Kristy Noem met with Netanyahu in Jerusalem, relaying Trump's message about the importance of avoiding actions that could derail the negotiations, an Israeli official said. Noem described the conversation as “candid and direct” during an interview with Fox News, emphasizing the need for unity and patience as the process unfolds.

Noem assured that the Trump administration would not prolong talks unnecessarily and expected a decision within days. She encouraged Netanyahu to coordinate closely with Biden, saying, “I asked the prime minister to work with President Biden to make sure we are taking wise decisions together.”

Meanwhile, Netanyahu’s senior adviser Ron Dermer arrived in Washington on Monday, accompanied by Mossad chief David Barnea, to hold discussions on Iran. The delegation met with Vice President Kamala Harris, White House envoy Steve Witkoff, CIA Director William Burns, and other top officials.

On the diplomatic front, Witkoff held talks with Iranian Foreign Minister Abbas Araghchi last Friday in Rome, marking the latest round of negotiations.
