The situation is not so simple.

Putin's regime has been the most pro-Jewish that Russia has ever had - Yes its a low bar, but nonetheless significant.

Putin has funded and supported Syria, but not Iran and Hizbollah. Russia put up with Israel blasting the later two in Syria every week for a decade, even when Russia troops got killed (because the Syrians don't know how to use an air defence system safely).

Yes, Ukraine has a President who comes from a nominally Jewish family. But he has been a fig leaf for substantial Neo-Nazi elements of the Ukraine armed forces - this was well recognised in Israel long before the current war.
