Hegseth Makes Unannounced Visit to Israel for Talks With Netanyahu Defense Secretary Pete Hegseth met with Prime Minister Benjamin Netanyahu and Israel’s defense minister, a week before a pivotal election.

Defense Secretary Pete Hegseth met with Prime Minister Benjamin Netanyahu on an unannounced visit to Israel on Monday, a day after President Trump publicly endorsed Mr. Netanyahu, who is fighting a tough election campaign. Mr. Hegseth made his trip after the Trump administration has expressed growing frustration in recent weeks over diplomatic efforts that have failed to produce a lasting deal to end the war in Iran, and Mr. Trump has threatened to launch new strikes.

Mr. Hegseth’s meeting with Mr. Netanyahu included Israel Katz, Israel’s defense minister, and took place at the Ovda Israeli air force base in the south of the country, Doron Spielman, a spokesman for the prime minister’s office, said.

The details of the conversations between Mr. Hegseth and his Israeli counterparts were not immediately clear. Mr. Spielman did not comment on whether Mr. Hegseth and the Israeli officials discussed attacking Iran.

He said they spoke about how the two countries were working together “against threats in the region.”Mr. Hegseth also visited troops with U.S. Central Command, which oversees American military operations in the Middle East. On Tuesday, he posted photographs of himself speaking with soldiers in front of a fighter jet but did not say where the visit took place or whether he had traveled to Israel and met with Mr. Netanyahu. Some American soldiers and refueling aircraft have been stationed in Israel since the United States and Israel started the war by attacking Iran in late February.

Mr. Hegseth’s trip to Israel and his meeting with Mr. Netanyahu were first reported by the news outlet Axios.

In late September, Mr. Trump suggested at the United Nations General Assembly that Washington could pursue renewed military action, and he threatened to “annihilate” Iran.

This month, Mr. Trump said on social media that he would not launch a new attack before the midterm elections in November. On Sunday, in a post thanking Mr. Trump for his endorsement, Mr. Netanyahu said that Israel and the United States would never allow Iran to obtain nuclear weapons.

The U.S. military has prepared new strike plans for Iran, including sending more forces to the Middle East, even as Mr. Trump has been inconsistent in his public messaging about the war.

Some analysts say they believe that the United States will most likely decide to strike Iran in the coming weeks or months, given how far apart the Trump administration and Tehran are in negotiations.

“The base line expectation in Iran, and in Israel, is that it’s a matter of when the war restarts, not if,” said Raz Zimmt, director of the Iran program at the Institute for National Security Studies, a Tel Aviv-based research group.

“An airstrike alone will probably not achieve the goals the U.S. and Israel hope to complete — but it might give Trump an image of victory and a way out of the war,” Mr. Zimmt added.

The Israeli election will take place on Oct. 27.

Polls suggest that Mr. Netanyahu is trailing Gadi Eisenkot, a former chief of staff of the Israeli military under Mr. Netanyahu. In a video statement on Tuesday, Mr. Netanyahu urged voters to support him, saying that he was the person Mr. Trump wanted by his side to “finish the job once and for all,” referring to the war on Iran.

On Monday, the Israeli military said in a statement that it had canceled soldiers’ leave starting on Thursday and ahead of the election.

Maj.

Gen. Eyal Zamir, the chief of staff of the Israeli military, said on Tuesday that the country’s forces were on “a high level of alertness and readiness” before the elections next week to safeguard against “external interference.”Adam Rasgon contributed reporting to this article.
