WASHINGTON (AP) — President Joe Biden and Israeli Prime Minister Naftali Bennett have postponed their White House meeting as Biden focused his attention on dealing with the aftermath of deadly explosions near the Kabul airport that targeted U.S. troops and Afghans seeking to flee their country after the Taliban takeover.

Biden and Bennett were scheduled to meet late Thursday morning for their first face-to-face conversation since Bennett became Israel’s prime minister in June. The two will instead meet on Friday.

Before arriving in Washington, Bennett made clear the top priority of the visit was to persuade Biden not to return to the Iran nuclear deal, arguing Tehran has already advanced in its uranium enrichment, and that sanctions relief would give Iran more resources to back Israel’s enemies in the region.

The Israeli leader met separately Wednesday with Secretary of State Antony Blinken and Defense Secretary Lloyd Austin to discuss Iran and other issues. The visit is his first to the U.S. as prime minister.

Bennett told his Cabinet before the trip that he would tell the American president “that now is the time to halt the Iranians, to stop this thing” and not to reenter “a nuclear deal that has already expired and is not relevant, even to those who thought it was once relevant.”

Biden has made clear his desire to find a path to salvage the 2015 landmark pact cultivated by Barack Obama’s administration but scuttled in 2018 by Donald Trump’s. But U.S. indirect talks with Iran have stalled and Washington continues to maintain crippling sanctions on the country as regional hostilities simmer.

Trump’s decision to withdraw from Iran’s nuclear deal led Tehran to abandon over time every limitation the accord imposed on its nuclear enrichment. The country now enriches a small amount of uranium up to 63%, a short step from weapons-grade levels, compared with 3.67% under the deal. It also spins far more advanced centrifuges and more of them than were allowed under the accord, worrying nuclear nonproliferation experts even though Tehran insists its program is peaceful.

Bennett's Washington visit comes weeks after Ebrahim Raisi was sworn in as Iran’s new president.

Raisi, 60, a conservative cleric with close ties to Supreme Leader Ayatollah Ali Khamenei, has suggested he'll engage with the U.S. But he also has struck a hard-line stance, ruling out negotiations aimed at limiting Iranian missile development and support for regional militias — something the Biden administration wants to address in a new accord.

Administration officials acknowledged that Iran’s potential “breakout” — the time needed to amass enough fissile material for a single nuclear weapon — is now down to a matter of months or less.

But a senior administration official, who spoke on condition of anonymity to preview the scheduled talks, said the administration sees the maximum pressure campaign employed by the Trump administration as having emboldened Iran to push ahead with its nuclear program.

Bennett is also looking to turn the page from his predecessor, Benjamin Netanyahu.

Netanyahu had a close relationship with Trump after frequently clashing with Obama. Biden, who has met with every Israeli prime minister since Golda Meir, had his own tensions with Netanyahu over the years.

During his latest White House campaign, Biden called Netanyahu “counterproductive” and an “extreme right” leader.

Biden waited nearly a month after his election before making his first call to Netanyahu, raising concerns in Jerusalem and among some Netanyahu backers in Washington that the two would have a difficult relationship. The president called Bennett just hours after he was sworn in as prime minister in June to offer his congratulations.

Jeremy Ben-Ami, president of the liberal Jewish advocacy group J Street, said Bennett is intent on building a positive working relationship with the Biden administration. But Ben-Ami, whose group supports a two-state solution to the Israeli-Palestinian conflict, noted that the two leaders are out of sync on several issues in addition to Iran. Bennett opposes the creation of a Palestinian state and supports expansion of settlements in the West Bank, which Biden opposes.

In an interview with The New York Times ahead of his visit, Bennett declined to comment on whether he would move to block Biden administration plans to reopen a U.S. consulate for Palestinians in Jerusalem.

“The warmth that is going to be projected and the good solid working relationship cannot fully mask the fact that the agenda that Prime Minister Bennett comes to Washington with and the agenda that the Biden administration is pursuing on some of the core issues are still almost as different as they could possibly be,” Ben-Ami said.
