Vice President JD Vance accused Iran of jeopardizing peace negotiations over Israel’s continued bombardment of Lebanon, insisting that the current cease-fire agreement with the United States had never included Lebanon.

Speaking to reporters in Budapest, after meeting with Prime Minister Viktor Orban of Hungary in an effort to boost the right-wing nationalist ahead of a coming election, Mr. Vance downplayed Israel’s continued strikes on the Iran-backed Hezbollah militant group in Lebanon, saying that the strikes in Lebanon had “nothing to do with” Iran, and denied that Lebanon was part of the cease-fire agreement. Lebanon’s health ministry said that 182 people had been killed in Israeli airstrikes on Wednesday.

“I think the Iranians thought that the cease-fire included Lebanon, and it just didn’t,” Mr. Vance said. “We never made that promise. We never indicated that was going to be the case. What we said is that the cease-fire would be focused on Iran and the cease-fire would be focused on America’s allies.”

He added: “If Iran wants to let this negotiation fall apart, in a conflict where they were getting hammered, over Lebanon, which has nothing to do with them, and which the United States never once said was part of the cease-fire, that’s ultimately their choice. We think that would be dumb, but that’s their choice.”

The vice president plans to travel to Pakistan for peace talks this weekend, beginning Saturday morning. Steve Witkoff, the president’s special envoy, and Jared Kushner, President Trump’s son-in-law, are expected to accompany Mr. Vance, Karoline Leavitt, the White House press secretary, said on Wednesday.

Prime Minister Shehbaz Sharif of Pakistan had said in an announcement Tuesday evening that “the Islamic Republic of Iran and the United States of America, along with their allies, have agreed to an immediate cease-fire everywhere including Lebanon and elsewhere.”

Mr. Vance also suggested that Israel had offered “to check themselves a little bit in Lebanon, because they want to make sure that our negotiation is successful,” adding “we’ll, of course, see how that unfolds in the next few days.”

Mr. Vance also echoed the position of White House officials who have said that Iran’s 10-point framework for talks that they have publicly released did not match Iran’s recent private communications with U.S. negotiators. The vice president dismissed those demands as “little more than a random yahoo in Iran submitting it to public access television.”

One of the proposals in dispute is Iran’s insistence that it be allowed to continue enriching nuclear fuel. Mr. Vance pointed to Mr. Trump’s stated goals of preventing Iran from building a nuclear weapon, and for the country to surrender its stockpile of enriched uranium.

Mr. Vance appeared to dismiss Iran’s request for the United States to affirm that Iran had a right to continue enriching uranium.

“My wife has the right to skydive,” Mr. Vance said, “but she doesn’t jump out of an airplane, because she and I have an agreement that she’s not going to do that.” He added that with Iranian officials, “we don’t really concern ourselves with what they claim they have the right to do; we concern ourselves with what they actually do.”
