Russian President Vladimir Putin and Israeli Prime Minister Benjamin Netanyahu attended a festive event at the Bolshoi Theater in Moscow on Tuesday as part of the celebrations marking the 25th anniversary of the re-establishment of diplomatic ties between their two countries.

“We are marking 25 years since the resumption of relations between us, and not only in culture and technology, but in so many other fields as well,” Netanyahu said, as he referenced the role that Russian immigrants play as a bridge between the two countries.

It is Netanyahu's third visit to Moscow and fourth face-to-face meeting with Putin in the past nine months, a sign of the warming ties between Moscow and Jerusalem.

During a meeting at the Kremlin, Putin and Netanyahu agreed to strengthen their regional military cooperation and to tighten their cooperation in the fight against terrorism.

“We discussed the continued coordination between our two militaries in the region, which already works quite well,” Netanyahu told reporters at a joint press conference in the Kremlin with Putin after their meeting.

We talked about the challenges to all civilized countries such as terrorism and radical Islam,” Netanyahu added.

According to an English translation of Putin’s words by the Tass News Agency, the Russian leader stated: “We spoke about the necessity to pool efforts to counter international terrorism. Israel knows only too well what it means and it is fighting against terrorism. In this sense, we are unconditional allies.”

“We attach great importance to our contacts with Israel, not only because Israel is one of the key countries on the situation in the Middle East, but also due to historical relations between our countries,” Putin said.

On Tuesday morning, Netanyahu lay a wreath on the Tomb of the Unknown Soldier by the Kremlin walls and inaugurated the interactive exhibit "Open a Door to Israel," a collaboration of Israel’s Foreign Ministry and Strategic Affairs Ministry.

The successful exhibit has been on tour in various capitals, most recently in Paris. The exhibit consists of nine doors, each leading to a different interactive portal showcasing Israeli accomplishments in technology, music and other fields.

"Israel's doors are open to Russia and Russia's doors are open to Israel," Netanyahu declared.

Netanyahu also visited the Kubinka Tank Museum near the Russian capital, where an Israeli tank is on display. Putin recently agreed to hand over the tank to Israel, some 34 years after it was seized by Syrian forces during the Battle of Sultan Yacoub on the fifth day of the First Lebanon War in June 1982. Three IDF Armored Corps soldiers -- Tzvi Feldman, Yehuda Katz and Zechariah Baumel -- are still missing in action from that battle.

During the visit, Israel and Russia signed a bilateral pensions agreement which “corrects a historic injustice regarding emigres from the former USSR up to 1992 who lost their eligibility for a Russian pension.”

Ties between Russia and Israel have never been closer, said Russia’s Chief Rabbi Berel Lazar, in an interview with The Times of Israel. Lazar and other senior leaders of the local Jewish community met with Netanyahu.

“There’s no question that if you think back 40, 50 years — even 25 years ago when the relations started, it was still very cold. Israel was taboo. I remember those days when we dreamed of the Russian president visiting Israel; it was something nobody thought would be possible,” the rabbi said.
