Holy shit dude… even Israel is defending itself (although without caring for civilians), not attacking. Are you seriously comparing Russia to Israel or even countries more or less allied with Israel? How delusional are you?
Besides that: all pollings show that the average Russian is pro-war. Its not ‘the ruling class’.
Hamas attacked Israel, Israel is defending itself against it, by invading Palestine. I don’t think that they are doing the right thing there and Netanjahu needs to be stopped, but initially they actually had a casus belli, which is a lot more reasonable than what Russia had.
