Israel will do what it always does and follow the advice of Aaron burr:

“Geniuses, lower your voices You keep out of trouble, and you double your choices”

They know Russia is supporting Iran and Hamas, but they also know Russia is a useful foil for US to make sure we never take them for granted.

It’s just chess, Russia isn’t a permanent enemy, and they’re always dumb enough to be manipulated usefully.

Mossad has sold US state secrets to Russia multiple times in periods which are disclosed. Who know what they are doing behind the scenes.

They always play both sides.
