JD Vance confronted Benjamin Netanyahu in a tense phone call, accusing the Israeli leader of being overly optimistic about the chances of regime change in Iran.

The Vice President told the Israeli leader on Monday that many of his predictions about the war which he had sold to Donald Trump had not materialized.

Despite the killing of Iran's Supreme Leader Ayatollah Ali Khamenei, hardline factions have tightened their grip on power and the regime remains firmly in control.

'Before the war, Bibi really sold it to the President as being easy, as regime change being a lot likelier than it was. And the VP was clear-eyed about some of those statements,' a source told Axios.

Vance, who reportedly advised Trump against going to war with Iran, was appointed by the President to help lead negotiations to end the conflict. 

A day after Vance's call with Netanyahu, a Right-wing Israeli news outlet owned by GOP donor Miriam Adelson reported that the Vice President had yelled at Netanyahu over Israeli settler violence against Palestinians in the West Bank.

White House officials, who described the story as false, began suspecting that Israelis planted it to try to smear Vance. 

An Israeli official denied that Netanyahu had planted the story and said his office issued a full denial when approached by reporters.  

The Daily Mail has contacted the Vice President's office for comment. 

Vance has been actively involved in diplomacy with Iran in the last few days as Trump seeks to end the conflict in the coming weeks. 

The Vice President met with senior Emirati officials, as well as the prime minister of Qatar on Thursday in meetings focused on ending the war and providing aid to Gulf allies. 

The White House suggested to foreign diplomats that Vance could lead a US delegation for high-level peace talks with Iran last weekend. 

Pakistani, Egyptian and Turkish mediators were told by the White House to tell the Iranians that their willingness to have Vance lead the talks was proof that Trump was serious. 

Trump on Thursday extended his deadline to not strike Iranian energy plants, writing on Truth Social: 'As per Iranian Government request, please let this statement serve to represent that I am pausing the period of Energy Plant destruction by 10 Days to Monday, April 6, 2026, at 8 P.M., Eastern Time. Talks are ongoing and, despite erroneous statements to the contrary by the Fake News Media, and others, they are going very well.'
