Israel’s premier stepped into the role of mediator on March 5 as the Russia-Ukraine conflict intensified, holding a three-hour meeting at the Kremlin with Vladimir Putin before calling Ukraine’s president and flying to Berlin.

Prime Minister Naftali Bennett’s sit-down with Putin was the first by foreign leader since the day Russian forces began the military offensive in Ukraine the previous week, and came after Kyiv had asked Israel to launch a dialogue with Moscow.

Bennett has so far walked a cautious line on the Ukraine conflict, seeking to preserve delicate security cooperation with Russia, which has a large military presence in Israel’s northern neighbour, Syria.

Bennett has not joined Western leaders – notably key ally the US – in forcefully condemning the offensive, instead stressing Israel’s strong relations with both Russia and Ukraine.

Ahead of his Moscow trip, Bennett had spoken by telephone repeatedly with both Putin and Ukrainian President Volodymyr Zelensky.

“Bennett’s action is bold but also risky. Much will depend on Putin’s state of mind,” Michael Oren, former Israeli ambassador to Washington, said.

Oren noted that while Putin rebuffed heavyweight diplomatic outreaches before the offensive, “Russia is in a different position today and Putin may be looking for a way out of his predicament. Naftali Bennet just may supply the ladder.”

Bennett’s office said he left Israel for Moscow early on March 5, itself an extraordinary move for a religious Jew who does not conduct state business on the Jewish sabbath, except in extraordinary circumstances.

Bennett and Putin met for three hours, in a visit that was coordinated with the US, Germany and France, an Israeli official said.

Bennett’s delegation included his housing minister, fluent Russian speaker Zeev Elkin, who was born in Ukraine when it was part of the Soviet Union.

The Kremlin said “different aspects of the situation in Ukraine” were discussed at the meeting.

After the Putin talks, Bennett called Zelensky – who is Jewish, has family in Israel and has visited the country many times.

Bennett then headed to Germany for talks with Chancellor Olaf Scholz.

The French presidency said Emmanuel Macron also spoke to Bennett before he left for Moscow on March 5, as part of joint efforts to “obtain a ceasefire in Ukraine”.

The top editor at the Times of Israel, David Horovitz, said Bennett’s trip had “extraordinarily high stakes”.

The premier’s “insistence on attempting the almost impossible – trying to maintain not neutral but warm relations with both sides in a war – is threatening to exasperate the US and has the potential to deeply harm Israel’s standing in the free world,” Horovitz said on March 5.

Quoting an unnamed source, prominent Israeli reporter Barak Ravid tweeted that the White House told Israel it doubted “Bennett’s chances to influence Putin’s position”.

The Bennett-Putin talks also “touched upon the progress of the [Iran] nuclear talks in Vienna”, the Israeli official said.

Iran and the International Atomic Energy Agency said earlier on March 5 after talks in Tehran that they agreed on an approach to resolve issues crucial in efforts to revive the country’s 2015 nuclear deal.

Bennett is a staunch opponent of global efforts to revive the agreement which gave Iran relief from sanctions in exchange for curbs on its nuclear programme.
