I think Israel would want to see Russia (and USA) out of Syria ASAP. They both just complicate Israel’s northern (north-eastern) border security.
Israel does not want peace in Syria - they benefit from chaos
Things were actually starting toward a brokered peace over the past 3 months - trump and the Russians were going to work out something even if the rhetoric didn’t match that
Israel ramped up its air attacks around Damascus ostensibly to take out Hezbollah but who knows - Russia threatened to take out their aircraft if they didn’t knock it off
Desparate times call for desparate actions
