WASHINGTON, Aug 28 ― President Joe Biden told Israeli Prime Minister Naftali Bennett in White House talks yesterday that he was putting “diplomacy first” to try to rein in Iran's nuclear programme but that if negotiations fail he would be prepared to turn to other unspecified options.

After a one-day delay due to a deadly suicide bombing in Kabul during the chaotic US evacuation from Afghanistan, Biden and Bennett held their first meeting seeking to reset US-Israeli relations and narrow differences over how to deal with Iran's nuclear advances.

Tensions complicated relations between Bennett's predecessor, Benjamin Netanyahu, who was close to former President Donald Trump, and the last Democratic administration led by Barack Obama, with Biden as his vice president.

But the meeting was eclipsed by Thursday’s attack outside Kabul airport that killed at least 92 people, including 13 US service members, confronting Biden with the worst crisis of his young presidency.

“The mission there ... is dangerous and now it's come with a significant loss of American personnel, but it's a worthy mission,” Biden told reporters after talks with Bennett.

US forces helping to evacuate Afghans desperate to flee new Taliban rule were on alert for more attacks, and on Friday night they launched a drone strike against an Islamic State target in eastern Afghanistan.

Speaking to reporters in the Oval Office, both leaders touched on Iran, one of the thorniest issues between them, but mostly they papered over their disagreements.

Biden said they discussed “our commitment to ensure Iran never develops a nuclear weapon.”

“We're putting diplomacy first and we'll see where that takes us. But if diplomacy fails, we're ready to turn to other options,” Biden added, without offering specifics. A White House statement issued later said the two also “reviewed steps to deter and contain Iran’s dangerous regional behaviour.”

Bennett, a far-right politician who ended Netanyahu's 12-year run as prime minister in June, was expected to press Biden in private to harden his approach to Iran and back out of negotiations aimed at reviving an international nuclear deal with Tehran that Trump abandoned.

US-Iran talks have stalled as Washington awaits the next move by Iran's new hardline president.

“I was happy to hear your clear words that Iran will never be able to acquire a nuclear weapon,” Bennett told Biden. “You emphasized that you'll try the diplomatic route but there's other options if that doesn't work out,” he added, also stopping short of identifying the possibilities.

Moving on from Netanyahu

Bennett has sought to move on from Netanyahu’s combative public style and instead manage disagreements behind closed doors between Washington and its closest Middle East ally.

But he has been just as adamant as Netanyahu was in pledging to do whatever is necessary to prevent Iran, which Israel views as an existential threat, from building a nuclear weapon. Iran consistently denies it is seeking a bomb.

Bennett told reporters that Israel has developed a “comprehensive strategy” to keep Iran away from nuclear breakout and stop its “regional aggression.”

Alluding to Israel's threats of military action and the billions of dollars in US military aid it receives, Bennett said: “It's our responsibility to take care of our fate, but we do thank you for the tools … you’ve been giving us.”

The visit gave Biden an opportunity to demonstrate business as usual with a key partner while grappling with the aftermath of the Afghan attack. His handling of the wrapping-up of the US military presence there after 20 years of war has not only hurt his approval ratings at home but also raised questions about his credibility among both friends and foes abroad.

On the Israeli-Palestinian conflict, Biden and Bennett remain far apart. Biden, according to the White House statement, reiterated support for a two-state solution, after Trump distanced himself from that longstanding tenet of US policy. Bennett opposes Palestinian statehood.

Biden made only a brief reference to the issue in his remarks. But the White House said he “underscored the importance of steps to improve the lives of Palestinians.”

Bennett did not mention the Palestinians in his remarks.

The consensus among Biden's aides is that now is not the time to push for a resumption of long-dormant peace talks or major Israeli concessions, which could destabilize Bennett's ideologically diverse coalition.

But Biden's aides say privately they hopes Bennett will make at least make modest gestures to help avoid a recurrence of the Israel-Hamas fighting in the Gaza Strip earlier this year.

Though the White House made no mention of Biden's opposition to further expansion of Jewish settlements on occupied land, it said he stressed “the importance of refraining from actions that could exacerbate tensions.”

Bennett, 49, the son of American immigrants to Israel, has been a vocal proponent of settlements.

The leaders also discussed “new opportunities” to expand Israel's relations with the Arab world, the White House said, after normalization agreements reached under Trump with the United Arab Emirates, Bahrain, Morocco and Sudan.

The delay in the meeting meant that Bennett, an Orthodox Jew who does not travel on the Sabbath, would remain in Washington until after sundown today. ― Reuters
