Putin's friendly attitude towards Israel can be explained in many ways.

First of all, there is a complex and long-standing historical relationship between Russia and Israel. Russia has been playing an important role in Israel since the Soviet era. For example, during World War II, the Soviet Union supported the founding of Israel. In addition, Russia and Israel have cooperative relations in many fields, including military cooperation, economic exchanges and cultural exchanges.

Secondly, Putin consolidated the friendly relations between Russia and Israel through active foreign policy and cooperation with Israeli leaders. Putin has established a solid relationship with former Israeli Prime Minister Sharon and cooperated closely during his administration. Russia and Israel also have close cooperation in the field of counter-terrorism, which is an important focus of Putin's foreign policy.

In addition, as one of the important roles in the Middle East, Israel has a positive impact on Russia's interests in the region. Russia is concerned about the stability and security in the Middle East, and maintaining friendly relations with Israel can provide some support and help for Russia's strategic goals in the region.

Finally, it should be pointed out that international relations are complex and changeable, and are influenced by many factors. Therefore, the above are only some reasons that may explain Putin's friendly attitude towards Israel, and cannot completely cover all factors.
