WASHINGTON (VINnews) — Vice President JD Vance confronted Israeli Prime Minister Benjamin Netanyahu during a tense phone call, accusing him of being overly optimistic about the likelihood of regime change in Iran and warning that key predictions made to President Donald Trump had not materialized, according to a report.

Citing a U.S. official, Axios reported that Vance told Netanyahu on Monday that the Israeli leader had “sold” the administration on an “easy” war scenario in Iran, including expectations that regime change would be more likely than has proved to be the case.

“Before the war, Bibi really sold it to the President as being easy, as regime change being a lot likelier than it was,” a source told Axios.

The reported exchange comes amid ongoing U.S. diplomatic efforts to manage the conflict in Iran and stabilize the wider region, including talks involving Gulf partners and other intermediaries.

The White House did not immediately respond to a request for comment on the reported call.

Vance, who has played a role in recent diplomatic outreach efforts, has also been involved in discussions with regional partners as the administration seeks to end the conflict and prevent further escalation.

Axios reported that Vance has raised concerns in internal discussions about expectations surrounding regime change and the trajectory of the war.

Israeli officials did not immediately respond to requests for comment on the substance of the reported conversation, Axios said.
